i was told that nightmares are just our brains sorting everything out like sometimes if we have regular dream and we remember them we can sit and think what did i watch are do or hear doing the day then i say oh yea i spoke about etc.. and we watched this movie aww that makes sense so i really try and remember that so that i don't let dreams or nightmares affect me to much i know it's my brain working and sorting everything out i see it as me being a huge file cabinet and my brain being a receptionist doing the filing lol hope that helps love steph
