Do you keep you eyes open while you are asleep?

I sleep with eyes shut. I can't imagine a sleep other way around. My friend, Thomas, sleeps like that. He knows it is bad, but he says he has no control. But there is no problem with the sleep too. The eyes actually rollback so that no light enters and brain thinks that it's as if the eyes has completely closed. And the problem is that dust and other stuuff get inside. Regards, Ajith.

I'm interested in knowing why its not good for you to sleep that way? I don't sleep like that but my 3 year old granddaughter does sometimes.

When I sleep I like to close my eyes to the rest of the world. There are people who are gifted with sleeping with eyes wide open. Cheers!!
