Aything loud, other than "good" music.
Close talkers. (not technically a sensation, but OMG I hate hate hate it)
The sensation of nuts, of any variety, being crunched by my teeth. It's akin to a sickening pain, and ussually I instantly retch. Hearing someone else eat them is also unpleasant, but tolerable.
Anything semi-loud, unexpected.
Sunlight. (Oh, the pain) Direct noonish sunlight in the summer can make me pass out in a matter of minutes. Strong light hurts.
Any smell from the paint thinner family. Mineral spirits, and nail polish remover included. Insta headache.
Grease, oil, lotion on skin. It's unnerving.
There is lots more, but, those are from the "avoid at all costs" list.
