Why do we get itchy and feel like something’s crawling on us when we look at insects like spiders?
In: Biology
The human brain is programmed to dislike insects because it associates them with decay, disease, and death depending on the insect, so when we see a bug, the brain tries to prepare you for the bug being on you, by imitating the sensation of a bug walking on u. In the case of some bugs, it also serves to make u check if there are any already on you, because oftentimes where there is one bug, there are many bugs.
