My mind is very strange when it comes to dreaming.
I was last time walking or something and I came into contact with those evil looking things on "Evil Dead" I lost most of what happened but I remember in detail, knowing, they were exactly those gooles off evil dead movie.
This is why I believe in photo-memory.... Why cant I have it!
The most disturbing for me was always how Id be living in this reality and things would be different and often bad as a result. But my family would always be sort of living and doing things but seemed almost unaware of me and while all of this was WRONG and unacceptable, everyone I know would be completely OK with it as if it were normal. Sometimes they would be living different lives and they wouldn't take notice of me and there was nothing I could do to interact with them. Sometimes it was certainly a nightmare.
Lastly, sometimes id be driving in the dark and someone In my family would be walking in the middle of the highway as some evil looking zombie but I knew who they were. And again id be left looking around me thinking "Why is this HAPPENING!? No one seems disturbed!!" I hate that kinda thing.
Usually those are stress induced dreams for me. The only other are, rare but sometimes, I feel like im stuck in an eternal reality where im stuck with this strange life and It honestly feels like ETERNITY. Then I wake up SOO relieved that none of it happened.
Usually I wake from those sweating in stress! But sometimes I actually have enjoyable dreams and am kind sad when I wake up.
This was an intersting article on why the type of dreams you have occur: http://luciddreamleaf.com/blog/types-of-dreams-and-what-they-say-about-your-brain/ There are actually ways to cause certain types (allegedly) via seretonin and dopamine chemistry.
