I have it happen pretty often where when I'm up late writing an essay, my keyboard that I'm typing with will start moving back and forth, then I'll have to keep readjusting my hands to be able to keep typing on the moving keyboard.
I will start hearing voices usually at a whisper level but other times normal talking level and rarely screams.
Then when I go upstairs to get ready for bed, the shower curtain always seems to be moving, and I'll see people in the corner of my eyes if I start getting too freaked out by the moving curtain.

And today I was reading an article on the computer and all of the sudden the text on one side of the page just started slanting upwards, like it was being pulled, but only one paragraph.

Does this happen to anyone else? I never really thought it strange until I told one of my friends about it and he never had it happen.
