Skepicism is healthy for a subject like OBE. The only reason I believe they are possible is because I've had two--one spontaneously at age 12, one purposefully at age 23. (And I'm still trying to do it again, but I haven't been able to.)
OBEs aren't something that you can hear and believe; if you haven't experienced one, then it seems flakey. How do you describe the color red to a blind man?

I am not sure that they weren't some kind of seizure or explainable phenomenon. Maybe people claiming OBE all just have a misfire somewhere in their head. Personally, I don't care what causes it; all I know is that I enjoyed my OBEs on a very spiritual level.
What you are describing sounds a lot like what many people describe as leading up to an OBE. I'm totally deaf without my ear toys (cochlear implant and a hearing aid), but during the moments leading up to my second OBE, which occurred after I lost my hearing, I experienced a loud, rushing, sound that increased in pitch until I found myself violently shoved "out" of my physical body and literally up the block to the area rec center. Strangly enough...
I sound like a nut, no? It's all good.
