I regularly have dreams where (It might sound extremely weird) I am in a place where it is fully dark red, and as if it couldn't get any weirder, I actually FEEL pain, and I am aware that I am sleeping (I can see the surrounding where I am sleeping, and ALSO the dream, like they're kinda flashing). And then, suddenly that dream switches, and I am in a fully white wall with a mint colored door, and something like the numbers "312" are written on the door. And then it switches again to the red place. It is extremely disturbing for some reason, and is there any reason for this? I have these dreams very, very often.
