'Sleep' in the Bible

In the second year of the rule of Nebuchadnezzar, Nebuchadnezzar had dreams; and his spirit was troubled and his sleep went from him.

Then the king went to his great house, and took no food that night, and no ... were placed before him, and his sleep went from him.

Now while he was talking to me, I went into a deep sleep with my face to the earth: but touching me, he put me on my feet where I had been.

But the sound of his words came to my ears, and on hearing his voice I went into a deep sleep with my face to the earth.

And a number of those who are sleeping in the dust of the earth will come out of their sleep, some to eternal life and some to eternal shame.
