I have a list as long as my arm probably of things that make me uncomfortable but here are the things that would be at the top of my list:
Visiting and having work done at the Dentist.  I need to have the gas and air everytime I go.  I get panicky sitting in that chair, having to keep super still with my mouth wide open.  It makes me feel very claustrophobic.

Spiders and pretty much all insects that wander into our house!

Sexy scenes in films… especially ones that are graphic/ noisy!  I’m not an even slightly prudish person but something about people doing the deed in movies makes me cringe and cover my eyes.

Hearing my voice on a recording/ video… and talking in front of a large group of people.

Having my personal space invaded.  This is a big no-no for me.  I don’t like people getting too close to me… this is part of the reason I could never be a dentist, a hairdresser or a beauty therapist and part of the reason I get panicky at a concert.  I don’t like being up close to people I don’t know.  My boys invade my personal space all the time and I don’t mind that 🙂

The biggest one for me is people fidgeting/ shaking their leg/ jiggling.  It sets my teeth on edge.  Just thinking about it is making me tense haha!

Anything to do with milk gives me the heebie jeebies… probably because if I taste milk, I throw up.  Even pouring milk on the boys cereal makes me hold my breath and pray that none of it touches my hand!

Clusters of dots/ holes… DO NOT EVER google Trypophobia!!
