Why do we for­get dreams so quickly?

How It Works - - BRAIN DUMP - Yusef Dem­sas

Sci­en­tists have sev­eral the­o­ries as to why we for­get dreams. Much of our dream­ing oc­curs dur­ing REM sleep, a deep pe­riod of sleep in which our bod­ies be­have dif­fer­ently to when we are awake. In REM sleep the sys­tems for mak­ing new mem­o­ries don’t seem to work as well, which is why peo­ple who wake up from dreams re­call them bet­ter, as there is a chance for them to pass into wak­ing long-term mem­ory. Our brains are good at fil­ter­ing out non-es­sen­tial in­for­ma­tion to con­cen­trate on more im­por­tant things, so per­haps most dreams just aren’t im­por­tant enough to re­mem­ber.
