There are a few reasons why we might dream, say neuroscientists. Even dreams that are scary may serve a purpose: One prevalent idea is that fear in dreams could help people deal with fear in waking life, much like exposure therapy. One University of Kansas researcher recently tested this concept. Garrett Baber, a KU doctoral student in clinical psychology, sought to test whether emotions experienced within dreams—like fear and joy—change feelings the following morning. The research is published in the journal SLEEP.
