Baby corn. Reminds me of some 50s sci-fi movie involving a shrink ray.
Wheels with 7 spokes. The 360 degrees of a circle do not divide by 7. It’s not natural.
Spiders. Not any kind of irrational fear, but a significant discomfiture. Upon finding them in video games, for example, I am most interested in resovling the encounter with haste.
Claustrophobia. Nothing clinical or chronic, but elevators and showers have always made me uncomfortable, unless they had at least one glass wall. This has gotten worse as I’ve gotten older, and the thought of attempting another MRI makes me uneasy right now.
Clocks that tick. Sorry, but that just bugs me. I try to ignore it but I can’t.
Women wearing neckties. As disturbing to me as a man in a bra.
