Last night I found out that if you roll your eyeballs backwards (as in look up) and kind of half-close your eyes, your eyelids start flickering really quickly, sometimes uncontrollably. And it reminds me of something I read a while ago about sleep cycles and how your eyes flicker when you're dreaming.



Oh it only works when you're a little tired. I've tried it when I'm awake, it doesn't work.
