“Trypophobia is a proposed phobia of irregular patterns, clusters of small holes or bumps." (...) The word is from the Greek: trýpa, meaning "hole" and phóbos, meaning "fear." Shapes that elicit a reaction include clustered holes in innocuous contexts such as fruits and bubbles.”Researchers hypothesize that the response is based on a biological revulsion, rather than a learned cultural fear. Upon seeing these shapes, some individuals experience shuddering, skin crawling, panic attacks, sweating, palpitation and nausea or itchiness.”
