When I was 5, in bed, I -saw underneath the covers- and a hand from nowhere grabbed my ankle, and shook it violently, growling in an harsh, admonitory, male voice “You shut up and go to sleep!”. This was not a paranormal entity, and it was not a hallucination, or a dream (contrary to popular opinions). I know this guy now, I managed to set us BOTH free! 🙂
