'Thoughts' in the Bible

as for thee, O king, thy thoughts came into thy mind upon thy bed, what should come to pass hereafter; and he that revealeth secrets hath made known to thee what shall come to pass.

But as for me, this secret is not revealed to me for any wisdom that I have more than any living, but to the intent that the interpretation may be made known to the king, and that thou mayest know the thoughts of thy heart.

I saw a dream which made me afraid; and the thoughts upon my bed and the visions of my head troubled me.

Then Daniel, whose name was Belteshazzar, was stricken dumb for a while, and his thoughts troubled him. The king answered and said, Belteshazzar, let not the dream, or the interpretation, trouble thee. Belteshazzar answered and said, My lord, the dream be to them that hate thee, and the interpretation thereof to thine adversaries.

Then the king's countenance was changed in him, and his thoughts troubled him; and the joints of his loins were loosed, and his knees smote one against another.

Now the queen by reason of the words of the king and his lords came into the banquet house: the queen spake and said, O king, live forever; let not thy thoughts trouble thee, nor let thy countenance be changed.

Here is the end of the matter. As for me, Daniel, my thoughts much troubled me, and my countenance was changed in me: but I kept the matter in my heart.
