The women in my family have all had experiences with what we call creepy men.
In the Early 90's, My mother had begun feeling uneasy in her bedroom and noticed a tall shadow figure who would stand in their corner watching her at night, he just became a part of life. A few years this continued on for he would just stand and watch until we were being evicted. A few days before we were due to move in to a new place. Mum woke up in the middle of the night to see him there as usual but he zoomed over to her and sort of illuminated himself (without casting light on anything else) She says he sneered at her and in a raspy whisper said "Jen". She tried to turn on the bedside lamp in a panic, forgetting that the globe burnt out earlier that day. She scooted to the end of the bed climbed off and backed up to the light switch for the main light all the while he was looking at her. The moment the light was on he vanished. She never witnessed him again after that.
I am 14 years older then my sister. I remember she was a happy toddler but sometimes would bold out of her room and cling on to my legs like she was scared. When she was about 3 she started talking about a man in her room. One night we were all lying on mums bed reading my sister a story. Sissi kept staring at the dresser at the end of the room. Out of nowhere she turns to mum and says so matter-of-factly " the man doesn't like you mummy". It was a bit unsettling. Shortly after that incident my sister was standing by the glass door just staring in to the yard. When question why, she got frustrated that we couldn't see what she saw. There was a man in a brown suit and hat in the yard picking grapes. As she got older she stopped talking about him.
When I was 21 I moved out of home and rented the house we lived in, in the early to mid 90's. That's when I got a creepy man of my own. When I would go outside for a smoke at night I would see a humanoid shadow standing freely in between the plum trees in my yard. At first I thought it was my shadow being cast across the yard but when I moved it just stayed there. One mid morning while I was hanging out laundry I looked up at the house and saw him there by the back door resting his arm on the door frame a bit above his head and it looked like he was looking at me. I couldn't make out too much of what he looked like because it was like looking at someone standing behind frosted glass. Even now I see tall solid shadows about 6 feet high dart across the main part of the open plan house. About 35% of the time its full on and not out the corner of my eye. While it does startle me I can cope with it. He doesn't seem to hurt any one.
I am not sure if it is all the same spirit or not I wouldn't mind getting out my video camera and a digital recorder and finding out.
