What you describe sounds like a DEILD to me, though the experience of HI indicates a possible WILD as well. Really they are both forms of WILD, so either way . . . .

Concerning your question about "rolling out of body": were you aware that you were dreaming when you rolled out? Did you maintain consciousness all the way through the transition from waking to dreaming? If so, then you WILDed (or DEILDed).
