I would guess that this is correct. My dreams are very much like half way between waking consciousness and a surreal movie - my consciousness doesn't seem to play a part in generating the surroundings and scenery and most of the plot, that seems to be the result of GenBrain.

I think daytime thoughts are also GenBrain btw. Only that waking brain has access to higher mental function - namely longer term memory, higher propensity to notice/surface inconsistencies etc.
