This part of the brain responsible for emotions and identify potential threats. During other tests had found an association between a decrease in feelings of fear and lowering levels of stress hormones norepinephrine   ( noradrenaline ) In REM sleep in humans. Scientists say that it is during REM sleep a person is able to rethink and overestimate the negative emotions and feelings about issues. As a result, after a full sleep a person often discovers his new powers to deal effectively with stressful situations.
