Her eyes were still closed, but she seemed to have fallen back into a more peaceful sleep.

And he doesn't look in any state for peaceful sleep; something's really bothering him.

Sometimes one goes off in his sleep, peaceful and quiet as a lamb.

The rest of the night passes in a peaceful sleep.

It was a peaceful sleep, and there were no more dreams.

I stayed by his bed until he fell into a peaceful sleep, which was in a very short time.

Then he fell into what seemed a natural and peaceful sleep.

The blue lakes of her eyes were closed in peaceful sleep.

The Indian closed his eyes, longing for a peaceful sleep.
