I hadnt experienced this until very recently, and was wondering if anyone else had ever done it.

Has anyone ever dreamed upside down ? Not as if you were upside down in your dream, but you were literally watching everything go on completely upside down. It happened four times last night, and I woke up thinking, "what the.. ?" And all of them were really scary.. One was in a room full of chains hanging from the ceiling, and this demented man/creature that looked like he came right out of a horror movie (except.. Id say a bit more frightening) was killing something.. and the other three were equally scary. One was only a flash, like a picture, but all of them were upside down. I could make out details and such.. just thought it was a bit strange.
