While I don't believe in ghosts or UFOs I love reading books on the occult, ritual magic and the paranormal. I've had some weird stuff go down that's unexplainable to me but I don't neceassarily put it into the realm of the supernatural.
Always my house (a condo) has had things that shake, wobble and rock. Sometimes it's lamps, sometimes pictures, sometimes cupboard doors. I've had the bedroom doors open when I'm the only one home.
Once when I was a kid I awoke and saw (or think I saw) a figure sitting at my miniature painting area. I didn't actually see the figure itself but the shadow on the wall as if there were someone sitting in the chair and their head/shoulders were shadowed on the wall. But that may have been some residual from a dream as I awoke but i always remember it.
Some stories from my mom are that she saw a black shape descend from the ceiling and leave a handmark on wall. She told me about it when I came home from work and there was indeed a mark of somekind on the wall as to whether it was a distinct handshape, that's up to debate.
Before she was married she was coming home from work late one night her car was bathed in a bright light from above, she stopped the car and covered her eyes and ducked down in the seat. When she came up the light was gone with no indication on the road or in the sky of what the light was.
Another time she was walking the dog before she left for work and saw a large rod shaped craft hovering over the lake across the street from our house. Later that day when she spoke with my grandmother on the phone she said she'd seen the same thing in the sky over our direction while letting the cats out at the same time that morning (granny lived some 20 miles away at that time). She didn't wake me, I think I was 12 at the time, I sure wish she would have I've always wanted to see something even as a kid. Any kind of proof we're not alone just whirling aimlessly around the void waiting for doomsday.
