“By analyzing the brain activity based on participants’ responses, we identified two brain regions implicated in the induction of fear experienced during the dream: the insula and the cingulate cortex”, Perogamvros explains.

The insula is also involved in emotion evaluation and regulation while we’re awake, and automatically activates whenever we start to feel afraid. The cingulate cortex, on the other hand, helps control reactions during threatening situations.
“For the first time, we’ve identified the neural correlates of fear when we dream and have observed that similar regions are activated when experiencing fear in both sleep and wakeful states,” Perogamvros adds.
