I mostly get complex geometrical patterns; I’ve never actually seen … images with a migraine, although on at least on two occasions, I’ve have had a smell — in particular a smell of hot buttered toast — with a strong sense that I was about 3 years old, being put in a high chair, and about to be given hot buttered toast, a sort of olfactory hallucination often goes along with recollection in that sort of way.
