from my experience, not to say i am right but it sounds more like you entered the second attention, not a lucid dream.

The second attention is a bit much to explain, so pretty much just say you were not in this world and when you are dreaming you are entering a lake into which it flows into an ocean( the second attention) it is alot to explain, most of this information you will find in alot of Don Juan work throughout history, back to the time of indian's they have talked about this.

But for you in that dream to actully feel objects around you, and feel as one, and you could "see" energy flowing from objects that's what it sounds like to me.
