Well, I think I might have had such an experience.
It was a few years ago while still in college (Binghamton University, NY), and I was all alone in the whole apartment building one summer night. For some reason, I was scared shitless and just couldn't sleep. I tried several times to sleep, but something would keep me up. Whenever I thought I was dosing off, I felt a strange sensation in my head and I would get back up, scared to go back to bed. Well, after a few hours I finally started to sleep.
Then, all of a sudden, I felt the strangest sensation in my head. I can only describe it as the sensation you feel in an aircraft as it's rapidly rotating. Sometimes you also feel it in elevators when your body weight gets lighter and lighter and you feel that sensation from your stomach going up. Well, I felt it from the bottom of my feet going all the way up to the crown of my head. Then, swoosh! I felt like something just came right out of the top of my head. It was a very strange, frightening and scary feeling.
For a minute, everything was quiet. I didn't know what had happened. I felt very peaceful, almost like floating on air. Suddenly, I noticed that something wasn't quite right. I noticed that I could see everything around me at once! It wasn't seeing actually, as the room was completely dark. It was more like perceiving things in the room. I could "peceive" my desk in the corner, and could tell that it was brown, and that my white computer was on top of it, even though the room was completely dark. I could "see" through the darkness with perfect clarity and knew where everything was, what everything was. It's the most difficult thing to explain, because I felt that I had no eyes to see anything. I just "knew" or "perceived" everything. Very strange.
I still had no idea what was happening. I wanted to get to another corner of the room, but had no idea how to get there. I had no legs, I had no hands. Bear in mind, I was still at this point clueless as to what was happening. Then, the strangest thing happened. I "willed" myself there, and suddenly, I was there! I had no explanation for it. It happened so quickly, I couldn't even tell how I did it. Then, I "perceived" the space above me and noticed I was touching the ceiling. Suddenly, I became frightened as I realized that there was no physical structure holding me up there, and so I felt I should immediately fall to the ground. Although I was not falling, I still became very afraid at being so high up off the ground, and before I think another thought, "swoosh", I felt myself sucked right back in through my head. I can only presume I was sucked back into my body.
I got up immediately, shocked, extremely frightened and shaken. I had no idea what had happened, nor could I explain it. For the rest of that night, I was so afraid I did not dare try going back to sleep.
For several days I treid to make sense of it, and said nothing to no one. Then, I noticed a few strange things starting to happen. For example, when the phone rang, my guess as to who it was calling ALWAYS turned out to be right. Well, I just kept saying to myself, "lucky guess". Then I began to wonder, is this really a guess? So, I started to accept it as fact, and I'm not joking, I always knew who was calling after that for some weeks, if not months.
A few days after, my housemate and his girlfriend came over. It was a lazy Sunday afternoon, and we were all in the living room just chatting. I was feeling lazy and tired, so I told them I'm going to take a nap, and left them alone. I then had the strangest dream. I saw myself lifting the roof off our apartment, like a doll's house and looking inside. Then I saw them making out and to my amazement, even having sex. I know this sounds very wierd, but I saw everything. Later that night I approached my housemate and told him what I saw, and to this day he accuses me of spying on them, for I described perfectly to the "t" what they were doing. He jokes about it all the time, but I keep telling him that I really saw it in a dream. Or sometimes I would dream of a place, or a situation, and a few weeks later I would find myself there in that same place and situation. Once I was making dinner in the kitchen, and suddenly I knew I was in that situation before. The tv was on, and I was even able to complete the sentence currently being said. I was in that situation before, I dreamt it in a dream. How on earth did I know what they were going to say on tv? I finished the sentence before the news reporter even got the chance.
Then, other strange things started happening. For example, I would meet someone, and suddenly I would have a thought about them in my mind. I would always dismiss this thought as just my being strange. A few days later my thoughts would then be confirmed as fact. Or I would meet someone and immediately know that we have something important to do. I even remember meeting this guy I had to work with, and the first thing that came to mind was that his wife was cheating on him. No idea why I thought that or where it came from. After about three weeks, we started to get to know each other well. He travels A LOT for his company, so we talked about aircraft all the time. Then, he mentioned to me how his family life is suffering because he always has to be jetting off to China or Indonesia or somewhere like that, and that all his wife does is take his money and ignore him. He then mentioned to me that he just found out she's been cheating on him with this guy from Paris. Incredible, I thought! And this is by far not the only example.
Well, shortly after my "out of body" experience, I met this Chinese guy who studied at the Shao Lin temple in China. He was visiting my housemate, but when I opened the door, it was like being knocked over by a wind. I knew immediately he was different, and that we would have something important to do. He looked me up and down, later he told me he was reading me like a book. I explained to him my experiences, and he explained to me these things about "out of body" experiences, energies, the whole works. I was really shocked and didn't know what to believe, until I started to have strange experiences with him. Like one day we went to the store, talking about a friend of ours, and I swear, he would read every thought I had before I even had the chance to say them. I would only open my mouth and he would already answer the sentence. I asked him, how did you know I was about to say that? He never answered, but for the rest of that night, he answered EVERY sentence before I uttered it. He taught me a lot about philosophy and control over one's emotions. He taught me that the true source of all negativity, and the real enemy within, is always fear. He taught me that it's our expectations (which are really just our fears projected) that ruin situations and relationships. Get rid of fear and expectation, and you'll finally be able to live a complete and "divine" life free of complications. So far I've done a lot along these lines, and I've gotta tell you, your life becomes so much simplier, so much more enlightened, everything becomes transparent to you, every need you have becomes automatically fulfilled - this makes you a powerful person. He demonstrated to me deep mind over matter techniques, things I could never do. I remember he once stopped breathing for a few minutes. Then, incredibly, I saw the hairs on his hands slowly rising up and down. I have no explanation for what that was.
Well, I could go on and on about my "out of body" experience. While I make no claim to being able to explain it, or knowing exactly what happened, it has left me with a hightened sense of awareness. I feel things I couldn't feel before, I know things I could have never known before. Although I'm no longer as sensitive as I used to be, every now and then I still get these feelings that I cannot explain. And they always turn out to be right.
I've heard many more incredible reports of out of body experiences. Mine is not so spectacular, but this is exactly as it happened.
