Is it normal that when i sleep my eyes roll back
When I am really tired and start to close my eyes my eyes have a straining feeling.... Like when you roll your eyes back too far, and you get that pain in your eyes.. I've noticed that this has been happening more and more.. It's hard to go to sleep when this happens too... And I've tried to keep my eyes straight but it's hard to go to sleep without your eyes being relaxed... Is it normal to have your eyes roll back when you sleep?
