"The hypnagogic state is rational waking cognition trying to make sense of non-linear images and associations; the hypnopompic state is emotional and credulous dreaming cognition trying to make sense of real world stolidity." [1]

Thank you for the clarification. I've never noticed any distinction between these two states. Perhaps that's why I conflate them. I suppose that stands to my point about the richness of autostimulated experiences.
