Alright so this was interesting and at least worth posting here for those interested.
I have been spending some time this week studying lucid dreaming and out of body experiences (again; tried this stuff before and never got anywhere with it). Anyway, last night I believe I had what one would call a lucid dream about having an out of body experience. It was probably the coolest thing I have ever experienced while dreaming. I'm still having trouble deciding if it was really just a lucid dream or if it was really an OBE.
Basically, I became lucid in my dream and then I guess I tried to have an out of body experience from there, within the dream. So I was trying all this stuff out like going through walls and flying. I could only barely get my hand to melt with the wall, but it was really neat. And flying didn't work. It felt so much like real like that when I jumped forward to fly, I actually "imagined" (I guess) gravity, and I fell down. I remember looking at my body wrapped up under the covers with just my head barely visible. And then last I remember going back into my body to end the OBE/lucid dream, then I suppose I dreamt some more and then woke up this morning not knowing what to think.
It was really amazing. I hope I can have more experiences like that; it's been years since I actively tried lucid dreaming or having OBEs, mainly because I stopped believing in some of it for scientific reasons. But I can't argue with first hand experience, so whatever it was that I had (which I'm thinking is just some sort of altered state of consciousness experience), it was really fantastic.
