english: Stress neurotransmitters in the brain are much less active during the REM stage of sleep, even during dreams  of traumatic experiences, leading some researchers to theorize that one purpose of dreaming is to take the edge off painful experiences to allow for psychological healing.
non_english: Neurotransmiteri stresa u mozgu su daleko manje aktivni tokom REM faze sna, čak i tokom snova o traumatičnim iskustvima, zato neki istraživači imaju teoriju da je jedna od svrha snova da ublaže bolna iskustva, da omoguće psihološko iscelenje.
