Stendhal Syndrome

" ... 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. The term can also be used to describe a similar reaction to a surfeit of choice in other circumstances, e.g. when confronted with immense beauty in the natural world."
