Is There Any Reason Why Someone Would All Of A Sudden Stop Remembering Their Dreams?

Question

well, my sister insists she ALWAYS remembers her dreams... but the past 2 nights she cant remember them. she keeps worrying and, quite frankly.... its annoying. i KNOW she is dreaming as i can hear her muttering and moving in her sleep, which is normal for her to do when dreaming. so, is there any reason i can give her as to why she has failed to remember her dreams that will SHUT HER UP?!?!? thanks in advanced!! =]

Answer 1

You only remember a dream if you wake during it. If you sleep all the way thru it, you won't remember it. If she is sleeping soundly, she won't remember them.  

Our dreams are just our brains way of moving data around. So rarely will they make sense. Since she moves in her sleep, she is probably used to waking herself.
