I have been having this dream for about 1 week now. Any ideas on what it means? Or how I can stop it? It really affects my sleep. Essentially, I 'wake up' in a white room tied to a white chair. I see someone staring at me, and then blood runs UP the walls, falls back down and the room starts flooding. The room keeps flooding until it gets to my nose/covers my head. Then I wake up. This dream can last anywhere from 30minutes-4hours, with me always waking up. Any ideas?
