Cyberwing and Quaffer gave you excellent advice. I don't think I would focus on this experience if I were you, though. Turn your focus toward Jesus and what HE wants you to experience in HIM- Satan is very powerful and will resort to all kinds of tricks to lure your attention from where it should be. I do know that sometimes God WILL give us a strange experience to shake us up and make us draw closer to him- I had several things happen in that vein a year or so ago- I had an issue in my life that I was not willing to let God handle (it seems ridiculous to have had such fear now, but it didn't then). I struggled with this for so long and God used many people and happenings (some rather strange) to bring me to the place where I would let go of this and trust Him. But, by far the one that really got me was the night I went to bed, had not fallen asleep but suddenly had this horrific sensation of being drawn upwards. I literally felt that my spirit was leaving my body and being taken to be judged. I could see my body still there on the bed. In an instant I knew where I would be ultimately spending eternity and I screamed, "I'm not ready!!" I cannot tell you how terrifying and final that knowledge was. I even saw this horrible demonic being waiting to take me away. Needless to say- God's message through that experience came through loud and clear. I think that if it (what you are feeling) is from God, you will not be plagued by any doubts about it. I know I wasn't. I knew God was trying to get my attention. And He got it.
