I once worked security for an abandoned mental hospital, then referred to as an Asylum for the Criminally Insane. I worked the night shift and there was all kinds of hair raising and creepy shit that would go on. Sometimes enough to keep you wide the hell awake. No danger of going to sleep on that shift.

I worked in a restaurant that was haunted. Used to f-ing terrified to be there alone. Cold drafts, lady with an old fashioned dress like a ghost from a movie disappeared around corner of the dining room a couple times (I will admit this might have been my imagination), stuff just randomly falling off walls (framed art) and shelves when no one was around, etc. I don’t expect anyone to believe this but it was nuts and a lot of people experienced it.
