Maybe this is like what people describe as " synthenasia " but I dn't taste or smell things...
synesthesia is the overlapping relationship of two or more senses (such as sound and sight, or sound and taste) or the automatic relation of graphemes (letters/numbers) with colors or personalities. if you were synesthetic, the sight of certain colors might trigger a subtle physical sensation--what you described is more like mental/emotional stimulation. but i could be wrong.
synesthesia is actually somewhat common amongst people on the spectrum; for instance i possess grapheme-->color synesthesia and sound-->sight synesthesia. there are a LOT of different brands of synesthesia, though, some of which may not have been reported yet. it's a confusing diagnosis, and you may have something of the sort.
