I keep missing the fact that the setting of my dreams are settings I have never been to in waking life, old strange layed out homes that I don't recognize and somehow does not tell me THIS IS A DREAM!!!

That or having my personal defense knife and it seems to go through the sheath and never stay in place correctly which is impossible, or things that keep changing colors....if that does not ring a bell I do not know what will that I was dreaming.
