I have far too many stories to tell at one sitting, but I'll give you a few short ones.
I was cleaning stalls where I boarded. All the horses were out, and I was the only one on the property. Smallish barn, with only 10 stalls. It was a privately owned place, not a public boarding barn.
I was in one of the stalls cleaning it, when I heard the door of the stall on the other end of the barn open, close, then footsteps walking down the barn aisleway toward me.
That particular stall door had to be propped open or it would fall shut on its own, so opening by itself wasn't something that would have occurred.
The footsteps walked past me, and out into the pasture. I didn't see anyone, just heard the sound of their feet.
Another time, I was watering the horses. There was a spigot with a hose attached at one end of the barn, and we watered the horses by dragging the hose to each stall. Typical situation.
As I was watering, I felt a tug on the hose. I figured I'd caught it on something, and tugged back without looking. Hose still felt stuck, so I looked up, and the hose was hovering above the ground about 6 inches, with a bend in it as if someone was hanging onto it.
I said, "Will you please knock it off, I'm trying to water the horses!", and the hose fell to the ground.
There were quite a few strange things that happened when I lived at that place, so yeah, I believe in spirits and other dimensions.
I believe there is a ghost in my house. I hear footsteps when I'm alone, funny sounds like someone drumming their fingers on the counter top, and one time the kettle even switched on and the light went off!
You'd think I'd have been pretty scared, but I wasn't. I've suspected for a while that it was a ghost, and one night, around midnightish, maybe 1 am, I came downstairs to get a drink, and I saw a little girl standing by the window. I am an only child in my house since my brother moved out, and I don't have a sister, so I knew this was a ghost. I suddenly felt so sad for her; she must have been only 6 or 7 when she died :( such a waste.
My mom doesn't really believe, but she's starting to. She believes the little girl haunts my room, which I think is nice, so sometimes I like to talk to her, and every now and then a pen will move, or my radio will turn on, so it's kinda like she's talking back :)
Ghosts scare me... but my little brother had an aboriginal friend that he used to talk to at our old house :)
At night he would cry because the man wouldn't get out of his room but during the day he would sit there for hours talking to him. I knew he wsant joking about this because he told me the aboriginal man had a white belly (ash) and he has never met an aboriginal before so he wouldn't of known
