http://en.wikipedia.org/wiki/Stendhal_syndrome
I can’t say that I’m a sufferer of this affliction, because although it happens to me quite often, it is titillating and makes one feel very much alive.
From the page:
Stendhal syndrome, Stendhal’s syndrome, hyperkulturemia, or Florence syndrome is a psychosomatic illness that causes rapid heartbeat, dizziness, fainting, confusion and even hallucinations when an individual is exposed to art, usually when the art is particularly beautiful or a large amount of art is in a single place.
