I don't necessarily believe in ghosts, at least not in the same way that other people do. But I don't think you have to believe in ghosts to believe in the supernatural, I have had some experiences that I cannot explain.
The first one was when I was about only about 13 or 14, still living in my hometown in Minnesota, and I think it was the first time I had one of my friends stay overnight, I had the upstairs bedroom, and we both had to go to the bathroom, which was downstairs on the ground floor.
He went first, and after I went, as was crossing through the living room, I saw what I took to be my friend duck down behind a lounge chair or easy chair in the corner.
I should also mention that he was a really "little guy" at the time, short enough and skinny enough that there would have been PLENTY of room for him to hide back there in that corner.
I just figured he either didn't think I saw him, so he was going to sneak up behind me and try to scare me on the way up or back in the bedroom, so I thought I could turn the tables on him by quietly making my way back up and either hiding or pretending to be asleep, so I could be the one doing the scaring.
But as soon as I got back up there, there was my friend sound asleep, dead to the world!
At the time I just thought I imagined what I saw behind the chair, it didn't really scare me, I went to sleep shortly after, and forgot and didn't think about it for at least around 10 or 15 years.
But after hearing about other people's encounters with the supernatural through various means such as TV, radio, and word-of-mouth, the memory of that night came back, which made me start to think that maybe I really did see something, and it wasn't just my imagination.
I've heard it said that it's not normal to remember your dreams, but in both of the last two apartments that I lived in I kept having dreams that I can't forget in which I couldn't escape the feeling of the presence of evil or demonic spirits. And in the case of the first one, I once had a dream where I was trying to "exorcise" the evil presence, and at one point I saw one of my SHOES floating in the air! Again, I want to make it clear that this was in a DREAM, not something I'm claiming to have really seen.
At another time in that same apartment I had a dream in which I was again asking Jesus to expel the demons, and what I can only describe as a "Scooby Doo Cartoon" version of a ghost (you know-kind of like a white sheet with a face...?...) reached out and grabbed me, which woke me up REAL quick!
However, in the LAST apartment I lived in a couple of things happened that can NOT be explained away as a dream. I usually work jobs that are second or third shift, and I was laying in bed mid-morning, probably unable to sleep because of neighbors making too much noise or any number of other reasons. Anyway, I was laying face down, more or less, when I felt something move VERY quickly under my chest, and then what I can only describe as I tiny fist or paw "punched" me on my chin or jaw. I never SAW whatever it was, and it didn't hurt, but it was hard enough that I definitely FELT it.
Not long AFTER that, I was AGAIN laying in bed in the post-sunrise morning, and I felt something like a small creature such as a rodent attack my foot with some tiny needle-sharp teeth and/or claws. But it only hurt for a few seconds, and it did NOT leave a mark!
So you all can believe whatever you WANT, but I have heard about and had too many experiences to say that there's nothing more to it than imagination or wishful thinking, especially since I did NOTHING to invite any of these things to HAPPEN!
