Well through my years growing up, there have been a few odd occurrences. The one that has been taking place between my ages of 3 to 7 on each Halloween, both me and my sisters would not go down our hallway to our rooms. The reason why, because at the end of the hall was my oldest sisters room, and as far as I can remember, when we looked down the hall we would see a guy, somewhat transparent standing there. So we would tell our parents, almost every year like clockwork, and they wouldn't believe us and go check. Of Course when they checked he was gone, but as soon as they left, he was back right there standing.
Here are some other experiences. On my moms mirror one time, there was this face imprint, almost like a smear, it didn't look mad or happy, more like trapped and trying to get out. Well we kept it there, and even my sisters friend would freak out when she saw it. Also an occurrence that happened to my sister. She was taking a shower and she heard a sound and looked out of the curtains and saw on the mirror two big handprints. I mean bigger than anyone's handprints that has been in our house. Another time my other sister was sitting at the edge of her bed, when she got up and moved, as she moved the glass globe-ball thing fell right where she was sitting and shattered. When I asked her why she got up she said she didn't know, she just felt she had to get up.
I have also had other occurrences, I would walk by sisters room, and see she had two doors to her room one from the hallway and another from the dining room(her room used to be a den) and the door from the dining room has a window in it. anyway, when i would walk by sometimes, I would see a face looking at me, of course when I went back real quick it was gone. I am still only 15, but things have calmed down, I don't remember anything dealing with something not supposed to happen but I still hear things, the only thing is, the sounds probably come from our cats, we only have 13!
