There’s one thing that has stuck with me for more than a decade (probably). It was a very short youtube video. It was just a man and women in bed back to back. After a second it pans to the woman’s side of the bed and shes a scary looking monster demon lady. I think about it once or twice a week. Specifically when laying in bed with my lady and shes not facing me.I have no idea what its from. Youtube used to have alot of randomly terrifying content.
