Hmm, never had this before.

I had something similar tho - in one of my LD's I decided to escape the earth. I was rising higher at very high speed. When I left atmosphere, all I saw was pitch black "screen". On this screen, I saw an explosion of words and phrases, made of red letters...
I dont remember what words said, but then I regained lucidity I was in a dream with extreme visual distortions and everything seemed very blurry.
