Having something sticky on me. Like if I unknowingly stuck my arm in a blob of jelly or honey or something. Gives me chills.
Being spoken to condescendingly.
Ongoing screaming / crying.
Finding a hair in my food.
Being lightly patted, like on the arm, top of the head, the back, etc.
Really loud cell phone talkers in public places like stores, etc. Makes me think they want everyone around to see and hear them talking and so believe they are such the VIP with their attention in high demand and so forth.
The aforementioned chewing and smacking noises of people eating. Also as mentioned, animals licking people in the face, especially at the mouth. Eww. And agree with the sound of humming being annoying, it always makes me think the hummers are furious about something and are trying not to explode.
Anyone but me touching my hair. Another thing that gives me goosebumps.
This is something I actually kind of like. Mainly having someone else brush my hair. I have thought before wouldn't it be a great to have a device similar to a salon type hairdryer where one could put their brush in a sort of mechanism so it can run it over your head as you sit under it? I'd love it.
