InstaSleep Reviews Team article notes:

• Research published in the Journal of Neuroscience found that people who spent more time in REM (rapid eye movement) sleep during the night showed lower fear-related brain activity when exposed to mild electric shocks the following day. The results suggest that getting good REM sleep can help protect a person from “enhanced fear,” the study authors wrote.
• The study is far from the first to reveal the benefits of a good night’s rest, particularly the importance of REM. Previous studies have found that the REM stage of sleep produces cognitive benefits needed to function when you’re awake.
