A condition called Charles Bonnet Syndrome can cause blind patients to hallucinate scenes in vivid color. fMRI studies show that these hallucinations activate the same brain areas as sight - areas that are not activated by imagination. Other hallucinations also involve the same brain areas as real sensory experiences. What's going on? Elizabeth Cox details the science of hallucinations.

This was a great talk! ♥ *I was really surprised, however, that you didn't mention the fact that no blind person has ever been diagnosed with schizophrenia.* To me, that's perhaps the most fascinating part, especially since the most common form of hallucinations for those suffering with schizophrenia are auditory. P.S. since everything we see is subjective, and is all experienced in the brain (for instance: how colorblind people see the world differently), isn't it technically _all_ a hallucination? :)

[@Graphomite]

Arguing semantics, but I think "illusion" and "hallucination" are different. Everything we sense could be considered an illusion. But I think a hallucination suggests a form representing something that cannot be confirmed by general consensus. The very chair you sit in could be some grand illusion, but the fact that others can confirm its existance and describe it as you do would suggest it is at least not a hallucination. If we want to go deeper and dismiss the idea of a general consensus by suggesting us observing others is in of itself also an illusion-- then we must define things by how consistant they are in our minds. Observing a pink elephant is a hallucination by definition because it is inconsistant. While a chair is consistant. But what if pink elephants become a consistant sight? So consistant, they are as ordinary to you as your chair? At that point, I don't think language is useful. At least no English language.

[@eldante4139]

I sometimes hallucinate voices when I’m waking up. A couple of days ago someone said ‘carpets’ and I woke up. I live on my own but he voice was as if someone said that standing next to me. I know it was a hallucination. I find that in dreams otherwise you don’t really ‘hear’ voices, you know almost the same way as reading off of a page what the other person has said. The voice that said ‘carpets’ was also distinctive away from my own voice and louder than my inner monologue.

[@thegreatestshenfan6484]

This guy by any chance? kzbin.info/www/bejne/bH-1eWCDaJ2YiNE

[@Willie6785]

I like how you put it in regards to dreams and voices. It always feels to me like everything I'm experiencing in a dream is part of a "script" of sorts. If it's a nightmare about something scary like a monster or such I'd feel anxious all the time during the dream, even more during worse moments of it, sure, but still I can "feel" it was a bad moment. If it's a good dream about something joyful happening, then I always feel light and happy all the time. As such, the events of the dream always feel like they're already something I should be expecting to happen somewhat.

[@sarahrivera4303]

i’ve also had a hallucination while waking up, and they are apparently pretty common when waking up and falling asleep. they have different names for visual and auditory ones but the only one i ever had was about a year ago, and it was vidual and auditory and im still curious about it.

How to locate the part where your eye is "blind". 1- Look straight forward, at a fixed spot, toward the horizon, 2- Close your left eye. 3- Extend your right arm and give a "thumbs up" to the horizon. 4- Move your extended arm to the left, keeping the thumb aligned with the horizon. You'll see there's a spot you can't see your thumb at all. Try moving it. It's like it's not there! That's where your retina cuts out and the optic nerve begins. It's around 10-15 degrees horizontally to your focal point and it is effectively a blind spot. It's where your brain interpolates the surroundings so you don't see a gray spot all the time. The brain also does this somewhat to your nose and eyeglass rims, if you use glasses. I used to wear thick rim glasses with relatively small lenses (I don't anymore. PRK surgery is awesome ♥). And you don't notice them consciently after using glasses for a long time, even though you're well aware of your deficiency.

Have hallucinated them for most of my life (approx 25 years), before they started to taper off.

having psychosis I can tell you the anti psychotics really work wonders I was extremely paranoid of them at first but when I changed to the monthly injection it really allowed me to step back from delusions and hallucinations and I felt like a whole new person. they come with a few side effects but its definitely worth it if your life is out of control and I can tell you they also really do effect how lsd works. I took some on a holiday with a friend and even after a few tabs It didn't have that much of an effect beside the body load and having a great sense of humour while my friend was really enjoying his trip. hallucinations can be interesting and fun but in every day life they can get in the way and the delusions can really break you down, if anyone is experiencing voices or thinking people are talking in code or the tv is talking to you these can be signs of psychosis and its ok to get health care involved because if it gets worse its hard to trust anyone including your own reality.

one of the must clear and beautifully explined videos thanks

[@erestube]

When I had a fever, I had hallucinations. At the time I thought it was my brain taking the easy route to showing me what I was looking at. It was kind of an imaginary focus. I guess this video confirms it!

[@TamarZiri]

This is so beautifully bade and so incredibly cute! filled me up with inspiration and need to create! thank you!

[@TommoCarroll]

Completely agree! Filled me up with a desire to keep on improving animation and design skills - these were STUNNING! The flow of the video and the style of the animation itself were beautiful!

I highly appreciate how this animation is done and how it communicates things.

One time i was trying to go deep in meditation and i thought i sleep but i was awake, and I don't get any visuals that are more normal but i was hearing and controling a whole orchestra, i was hearing every instrument and i was able to focus on then individually, i never have heard this song that was playing, it feels like i was creating the sounds all at same time, it was beautiful

I am a teenage deaf girl who is on KZbin a lot and you have just help so much as I have had hallucinating voices. Thanks for letting me know what was happening. Yours sincerely a teenage deaf girl👂

[@AxolinaAxolotl]

When you look at a mirror in really dim light, almost all of what you see is a hallucination.

[@AxolinaAxolotl]

@Hedgiethe Hog just look at yourself for 10 minutes. No distractions. You start to slowly see distortions in your sight. You might not even be able to identify yourself anymore. There’s even a study for this

[@christyjoseph8963]

@Hedgiethe Hog yea i get that too

[@Quazi-moto]

@@AxolinaAxolotl Yep. Candlelight is best for this. Just stare at your reflection or another person... it will change drastically and many times.

Not here to encourage drug use, but I believe psychedelics, when used properly and with respect; can be a very positive, introspective and meditative tool. LSD, DMT, Ayahuasca, Psilosybin, Peyote- all hold a place than can benefit us when used in a way that promotes insight to the world around us. The concept of an 'ego-death' is, in the moment, often scary, awful and profound; but when you come back to a sober state, it allows you to reflect and feel humbled, almost. Able to see things in a new light and hopefully gain new respect for things you may overlook in daily life. You see details you never would have noticed. Feel things that you may have ignored otherwise. Often times, people generally go back to a child-like state of understanding. Not in a 'childish' way necessarily, but in that your perception changes to see things fresh and in a new light. One you may have never considered before.

[@riddlezastra1496]

hahahhaha you started with "Not here to encourage drug use.." and then TOTALLY endorsed drug use in the next ten lines.. so much so that I'm convinced LOL

[@okeoi]

@@riddlezastra1496 Haha, well, I don't think talking about psychedelics in a positive light is specifically endorsing or encouraging their use. These are just my beliefs and what I've experienced. The one thing I do encourage everyine to do is research for themselves.

[@riddlezastra1496]

@@okeoi Sure.. I am ALL for that, actually.. but you know there are things like psychosis, bad trips.. and impulsive and dangerous behavior ("I believe I can fly") so maybe it's not for EVERYBODY, that's for sure.. but there is this study that says that microdosing everyday has cognitive benefits and stuff.. so maybe that'll work for all of us

I had only one auditory hallucination when I was a kid. I was by myself and remember vividly being alone in a park near my house. I heard someone whisper in my head and I immediately looked behind me to find nothing. I don't know why it happened, now I only have these occurrences in the twilight zone of sleep, but it was as clear as any voice I've heard. And I'm positive it was in my head as no trees or places to hide to were around. I wonder if I conjured up this memory but it couldn't have been the case, As I remember every detail to the letter.

[@anissa911]

gmmg same, i had a few auditory ones when i was younger, they never came back

No, it's them substances ) I mean, including those naturally present in the body.

[@Chronically_ChiII]

Our consciousness is a product of the working neurons of our brain and we have no free will over it. *That* is why we can be controlled by biochemical interaction of ingested drugs, because we are already controled by the existing drugs in our brain.

[@janehates]

These animations are absolutely gorgeous!!

[@rosequartz4102]

I've always been too afraid to take hallucinogens but I remember a few times hearing such real classical music while I was trying to fall asleep. It lasted for 5 or 10 minutes. There's no rhyme or reason for it. Great video!

[@kingo549]

It was the day before my 9th grade result of BOARD exams and I was so much stressed out it literally was nerve racking at last I finally slept at 🕝 two thirty n then I woke up at five to Offer prayer (I’m Muslim) and I clearly remember that I was standing and due to extreme sleep deprivation my eyes just closed themselves and I literally saw the same scene but everything was dark mustard in colour and I also saw three to four ME(S) standing on my either side and then I subconsciously say in my mind NOW WE ALL ARE GOING TO PRAY TOGETHER and then I open my eyes just at that moment all of the other ME(S) fuse with me ...I was so scared I immediately finished the prayer and then went to 🛏 bed !!!... I remember that vividly for sure... As a side note I scored 97% ( not bad though) Also I’m myopic but wasn’t born with it Does it mean I have C.......?😱

[@janarabarr5428]

Maybe u were just stressed.... I got hallucinations when I was highschool bcos of depression which causes lack of sleep, crying every afternoon and always alone. I even saw my feet standing in front of me and it was creepy, I even heard someone like a old lady calling my name with a thirsty sound (they were all sleeping that time except me bcos I had insomnia)... For now I stopped hallucinating (maybe) bcos I overcome my depression but I only hallucinate when I'm having sleep paralyze...

Wow I've had nearly the same exact vision of my room being dark and yellowish when I close my eyes, only difference is I was tripping lol. You were probably in a very meditative state from praying which can cause some strange things to happen

[@stonesheeva7158]

Every trip can be a bad trip depending on how you perceive it. I've been in a room full of people on LSD and we all seen the same exact thing. Or the same exact thing happened to us during the trip that seemed to stand out from the rest of the trip. I believe it lifts a vail of what normal perceiving people see. I also had a near death experience and was completely Atheist "Never religious in my life" before this happened. I saw my entire life "Like a movie" play out in front of me. Then I was shown a baby sitting in the middle of the bed with her arms out wearing a ponytail on the top of her head. Then I awoke looking down on myself from an aerial view staring down at my own body. I couldn't see or feel my body from where I was. I only had my thoughts, my sight, and my hearing. I could hear people from below me frantically trying to revive me. I felt calm, warm, like a baby being cradled by it's mother. I was slowly drifting upwards ever so slightly as the seconds past. I asked questions in my head and they were all answered. I was eventually revived and a year later had a baby girl that looked exactly like the little girl from my "Life review". The whole time I was floating I felt as if someone was next to me but I was never able to turn to see who it was. I knew from that moment there is more to this world than we could truly ever understand. Almost feels futile sometimes. Especially to explain it to others. Near death experience studies are fascinating. Seems to hold a lot of keys to the answers of consciousness and the human brain. I was experiencing thing I shouldn't have been experiencing in a time when I should not have been conscious at all. I was dead for 15 minutes.
