Can endermen enter your house when you sleep?

Since they can move blocks, imagine that endermen made a hole in your wall so monsters can now get in and disturb your sleep.

Could that be possible ?

No.

Time does not pass, in the normal sense, while you sleep. Instead, the game checks to make sure you are "safe" when you go to bed. If you are, game time "jumps" to dawn. Crops don't grow, dropped items don't decay, and monsters don't move. The only way you can be woken in the middle of the night is if you weren't safe when you went to bed.

No I do not think so. Unless you have the Somnia mod which I do not think is updated to 1.8 yet. But you should be safe unless you are right next to a enderman
