Daniel 10:7-9

And I, Daniel, alone saw the vision, for the men who were with me did not see the vision; but a great terror fell upon them, so that they fled to hide themselves. Therefore I was left alone when I saw this great vision, and no strength remained in me; for my vigor was turned to frailty in me, and I retained no strength. Yet I heard the sound of his words; and while I heard the sound of his words I was in a deep sleep on my face, with my face to the ground.
