like motor and pre-motor cortex, occipital areas, visual cortex, but actually there's a big debate whether it involves the primary visual areas, areas 17 in the human, OK, so most studies are saying that the activation does not reach the occipital pole, it gets those secondary, tertiary areas, OK? and then there is the amygdala, hippocampus, thalamus of course, the pons which generates REM sleep basal forebrain, and anterior cingulate, all those regions are active during dreaming during REM sleep, sorry
