Is there a way to tell if a snake is sleeping?

OH I just realized I totally misunderstood your first post. Guess seeing MR Snakes' reply and then yours confused me. I somehow thought you meant "their eyes become the shape of the clock's hands at 6 o'clock" (which is a huge stretch now that I think about it LOL) but now I see you mean 6 o'clock as in the location of the round pupil in the eye /facepalm

LOL, round pupils sink like a sunset to the 6 o'clock position when snakes are asleep. Don't worry, MR Snakes is an equal-opportunity-confuser...
