The Mezmerizer MV actually uses real hypnosis techniques!!! It’s very well researched!! Flashing lights and quickly appearing and disappearing words are a common method for suggestion. The video often points the viewer’s attention toward a point of focus and then shows things in the peripheral view that you aren’t supposed to focus on (this is often why people use spirals in hypnosis, to focus the eyes.) And a community post details that you should focus on the center point, turn up your device’s brightness, lower the brightness of the surrounding room, and max the volume preferably with headphones. These are all things that would make hypno more effective! It’s impressive!
