Out of body experience?

Ok, I know thisll probably sound really weird, but lately sometimes when I try to go alseep, I get this weird goosbump feeling all over my body, and if I think about people I get more goosebumps, and then I swear Im flying, I can see and feel my spirit floating out of my body, it is scary. I know Im not dreaming, because I can think and feel and hear during this and I can think about how I am not dreaming too. I start flying faster and faster and I can still feel myself getting goosebumpy and hard, and by the time I fall back into my body my body is super hard and I have to just sit in myself for a minute before I can even move. Is this some wierd form of astral projection or and out of body experience?? Id really like to know if this has happened to anyone else. Im only 13, and Im freaked out,
