Weird experience...not sure what to make of it.

It's been a while since I posted on this site, first time in this section. I just had a rather...unsettling experience that i hope someone here can shed some light on. This seemed like the most appropriate place to post. Basically, I was lying in bed on my left side, trying to get to sleep. I don't remember exactly what lead up to it, but I started experiencing a rushing sound in my ears (like I do when I WILD, it sounds like white noise coming from inside my head). So I thought, "I haven't slept at all, this probably won't be a dream, but I'll go with it and see." My body felt very strange, almost distant. I was able to shift a foot a little, but it felt odd, like really 'muffled' i guess is the best way to describe it, like I was in a pool of some kind of jello. I started hearing a sound in my ears again, but not like before...this was like breathing, steady breathing like of someone asleep. This is where is gets weird. I felt myself breathing a little irregularly, but i heard a deep, steady breath in my ears. Next, i felt my body rocking from side to side, but stiff as a board, like I was a statue. I think I could almost see my arms in front of me, but I can't recall for sure. Finally, I felt the sensation of sliding out of my body from the side. As this happened, there was a ringing in my ears that got progressively louder and more harsh, and it felt like my movement was speeding up. I was starting to mentally freak out at this point, and soon saw my room fade into view, I was awake in the same position i had been in before. That's it. I guess my main question is could this have been the beginning of an OBE, or astral projection or whatever? I've only ever briefly looked into this sort of thing, and that was a while ago so I really don't know anything about it. Any similar experiences? Thanks in advance!
