It's very possible to sleep with your eyes open. Lots of people do it but their eyes are never opened all the way. Have a look at these http://www.wikihow.com/Rest-with-Your-Eyes-Open and http://vision.about.com/od/sportsvision/a/sleepingwitheyesopen.htm for more details.

Yes it can happen, but most people, their eyes are half way open half way closed
