I wondered this evening if music ever appeared in dreams, and looked it up: apparently so, especially among musicians.
I wonder if this is something "trainable" or reflects a personality trait. I never dream of math or physics (or discover a benzene ring in my sleep), so what's in the dream isn't just a matter of what the interests of the day were.
Vision, always. Speech, usually--but not other noises as a rule. Touch--in only one category. Taste--never.
We've heard aplenty about the meaning of the contents of dreams. Does what kinds of senses are involved in a person's dreams tell us anything about him? (I'm not looking for stresses or pathologies here.)
