did you ever?

Did you ever experience to sleep and feel that your eyelids are covering up your sight.?One night, I lay down on my bed to sleep from a very long and wary day. when I close my eyes after praying, I can imagine myself that my eyelids are covering up my pupils that enable my eyes to see. It's a really weird feelin. I can bearly breath that time so I open my eyes immediately. Who's with me? if you are,close your eyes. hehe.:)
