Seeing cluster of holes in pictures or in person gives us unexplainable creeps. The reason exactly still we don't know. But science says there's a deeper reason behind our aversion.Trypophobia is the fear of cluster of holes or bumps. Our great repulsion from corals and honeycombs are the best examples of this phobia. Jitters from things or images with little holes isn't the brain tricking us again, but actually its way of telling us there may be harm. http://imgur.com/gallery/sH2tqKT Arnold Wilkins and Geoff Cole of the University of Essex's Centre for Brain Science were the first to publish studies regarding this phenomenon. They said it could be a "biological revulsion" or a cultural fear we have subconsciously acquired. Wilkins and Cole published an article in Psychological Science, indicating that seeing obnoxious images of holes that are actually innocuous is our brain associating the holes to possible danger. Our brain, carries a somewhat DNA-acquired fear from our ancestors that little holes mean peril. The brain links it to holes made by harmful insects, or fearsome animals such as the tentacles of octopus. People with trypophobia say seeing similar images with icky burrows make their skin crawl. Some say they get panick attacks or feel nauseous, some have palpitation, itch, or sweats when they see cluster of holes. Other people with trypophobia say they think unknown creatures may be living behind the hollows. Thus, if this you find this mac n' cheese burger horrifying rather than tempting, I feel you. It's just our brain trying to keep us safe.
