Did you sleep with her?
After answering my questions, he slept on.
Do not fasten all the windows up while you sleep.
The noise redoubled, and sleep was out of the question.
He likes to sleep curled up on his side.
He likes to sleep with his knees drawn up.
Why, she sleeps with him!
Sleep in it every night?
I can do that in my sleep!
What time would you wake up and go to bed?
I looked over at them. They were sleeping.
Why do we sleep?
