Lucidity.
My dreams are so vivid and intense. I guess thats a good thing...I wouldn't want monochromatic dreams, but sometimes its difficult to become lucid in such a realistic dream. I forget to look at my hands when theres no apparent need to. I forget to look for the purple wall. There's always a purple something...a wall, a room, a door. Its just that one shade of purple that reminds me..."oh yeah, its a dream". I woke up this morning, to "Here comes your man" by the pixies...but it was only in my head.
