'Sleep' in the Bible

Now in the second year of the reign of Nebuchadnezzar, Nebuchadnezzar had dreams; and his spirit was troubled and his sleep left him.

Then the king went off to his palace and spent the night fasting, and no entertainment was brought before him; and his sleep fled from him.

Now while he was talking with me, I sank into a deep sleep with my face to the ground; but he touched me and made me stand upright.

But I heard the sound of his words; and as soon as I heard the sound of his words, I fell into a deep sleep on my face, with my face to the ground.

Many of those who sleep in the dust of the ground will awake, these to everlasting life, but the others to disgrace and everlasting contempt.
