Title. Is this just a symptom of anxiety or overactive imagination? What’s actually causing those sensations and is there a purpose to them?
In: 34
Your brain is basically a neighborhood of neurons that activate when stimulated. Often neighbors activate each other. Usually the neurons that cause you to feel prickly can only be activated by the neurons that see bugs, or feel them actually crawling on your skin.
However, sometimes it’s enough for you to imagine that bug, and that’s sufficient stimulus for the prickle neurons to activate.
