Our dreams' weirdness might be why we have them, argues new AI-inspired theory of dreaming

Why we dream is a divisive topic within the scientific community, and the neuroscience field is saturated with hypotheses. Inspired by techniques used to train deep neural networks, a neuroscience researcher argues for a new theory of dreams: the overfitted brain hypothesis. The hypothesis suggests that the strangeness of our dreams serves to help our brains better generalize our day-to-day experiences.
