Obe- And A Little Fearful

First off let me state that I just want to know what I am going through, and with all the information out there it is hard to figure out what exactly I am going through. I am also not the best story teller or talented writer.

I went to sleep like any other night when I woke up and found that I couldn't move my body at all, no matter how much I tried. I do remember the tingling sensation through out my entire body, as if my foot fell asleep but all over. It had felt like minutes had gone by when I closed my eyes, upon reopening them I looked down to see my self sleeping. In that moment it felt as though I was a kid playing with two magnets holding them apart trying to feel the pull between the two, when I was pulled back to my body. I was a little freaked but pretty out of it, I tried to just roll over and forget about it. I then felt something "hand like" grab my left shoulder, at this time I couldn't move my body again and a little angry because I thought my roommate was trying to wake me up. I then, what I could only describe as sheer force of will which seemed like forever, moved my hand and grabbed the hand on my shoulder. Upon looking at it, the only way I could describe it is, it was a black long hand with thin fingers, a little freaked, I said, "No! Go away!" Then instantly rushed to turn on my bedroom light about 6 feet away. When I made it to my light switch I tried to flip it on, and couldn't make contact with the switch. I then turned around and seen myself sleeping, also looking for whoever grabbed my shoulder and nothing else was in the room. I was pulled like the magnets again back to my bed, then the full body tingling returned. I guess I fell asleep because nothing else happened and I woke up the next day. Just in awe of what happened the night before. I asked my roommates if they tried to wake me up or come into the bedroom, and I guess none of them did and they had turned in early as well. I read about "out of body experiences" and "body paralysis" and looked into the hand I seen and grabbed. Everything has just left me with even more questions then answers. I am also unusually tired and exhausted and haven't done anything out of the ordinary outside my normal routine. I just feel drained. I have just been trying to come up with reasonable explanations and answers. I truly believe I had an out of body experience. As for the hand? I have no idea but that leaves me with just as many questions and the need for understanding.
