Published in the Journal of Neuroscience, the study conducted states that people who spend more time in rapid-eye-movement (REM) sleep – where dreaming occurs – had lower fear-related brain activity when given mild electric shocks the next day. This suggests that sufficient REM sleep before fearful experiences may make people less susceptible to post-traumatic stress disorder (PTSD). Read article here.
