When I took psychology a semester ago, my teacher insisted that she has never heard of the word. When looked up in Merriam Webster's Dictionary, it did not pop up. Do medical professionals use this term, it is rather weird as I don't think we just intuitively look at something and then have a weird feeling. I only get that weird feeling when looking at a picture that I see from looking up trypophobia. I noticed if I don't explicitly think about it, it does not affect me. Also my computer believes the word does not exist, as it believes trypophobia is spelled incorrectly.
