I sometimes have dreams that appear to last for months, even years, as if I fully lived it. Sometimes it's like being some kind of Jedi in a big war and I realize instantly it's a dream and I enjoy it to the fullest as I'm in full control. But other times it's getting a successful job and a perfect relationship, also feeling in full control, only to wake up some day again and be completely disoriented and robbed from what appeared to be a perfect life.
These dreams leave deep "scars" for a better word, if I think about them pictures start to form inside my head but they never become fully clear, but the feelings are sooo there and soo intense. It's like the feelings were there before the story and my dreams put those wants/desires into a story to give them a logical place.
It makes me wonder about how the brain processes information and how pictures are important for feelings to have something to tie to. I'll ramble a bit now; but it makes sense if you think about for example a "father/mother figure", someone just needs "something" to tie certain feelings to, and not being able to sort feelings under different kind of pictures may cause problems later on "in society" when someone has to draw certain feelings from a certain place and may incidentally call upon other feelings too as they were "tied" to the wrong picture. I mean, "the boogey man" or "the monster under the bed", is something that all children of all cultures experience on some level, and that could be the function of tieing certain fears and such to something that isn't really there. If you got "other worries" you may tie your "nonsense childhood" fears to for example the idea of being a father.
