nightmare

I found it difficult to get to sleep last night, when I eventually did I think it was some time around 3am.
I had a dream that I was at my computer, and suddenly I was pulled through the screen, I was in a white void sort of space, like a blank document on word. But then huge letters started appearing, I couldn't read them but they where going to crush me. I was running but couldn't tell how fast I was moving, because all I could see was white empty space.
Then I woke up.
