Ghost knocks off trashcan lid April 29, 2020

Laying in bed in the AM we heard a loud noise. Did not think anything of it. The dogs perked up and I went to investigate. Did not notice what had happened until I watched the video cam footage. Then went in to put the lid back on the can. Then it occured to me all the doors were closed and there was no reason we could think of for it to flip off like that. Furthermore, this is the first event we caught on camera. Other events had no proof so we kept our traps shut.
