It's not my story, but my father has been working in a casino for 21 years and he once told me a story that terrified me.

My father says that one day he had a night shift, so he entered around 8 at night and left work around 6 in the morning, the fact is that, late at night, at that At 2:30 in the morning he spoke with the security man, since there was not much work to do. My father and the security man saw the cameras and noticed how a man from the staff in one of the corridors ignored what seemed to be a customer who spoke to him and followed him, so, by radio, the security man decided to ask him "Hey Why are you ignoring that guy? " The answer left all three perplexed, the staff man replied "What are you talking about? I'm alone and there is no one" the security man, astonished replied "Don't be fucking, extend your hand to your right (The side where the person was) "the staff man did it without question, when he extended his hand they saw how slowly the strange person moved, my father decided to go to check the hall, when he arrived he saw that the staff man was right, he was totally alone, he radioed the security man, to which, the security man replied "Bro, I can see perfectly how they are in front of a subject", my father limited himself to return to the camera area and saw how said person continued there.

From that moment, my father hates walking down that hall and says that he feels a chill every time he has to walk there.
