It could be an OBE... but hard to say without feeling your experience by myself. I feel distinct difference between OBE(it isn't important to which dimension, even if mind state is distinct from dimension to dimension there is feeling of sharp "reality") and lucid dream(where you know, that that is a dream).
I do my OBE's from waking state, not from a dream. Also LD's I do more often from waking state than from a dream.
