Jeremiah 23:17, 25-26, 32

They say still unto them that despise me, The LORD hath said, Ye shall have peace; and they say unto every one that walketh after the imagination of his own heart, No evil shall come upon you.

I have heard what the prophets said, that prophesy lies in my name, saying, I have dreamed, I have dreamed. How long shall this be in the heart of the prophets that prophesy lies? yea, they are prophets of the deceit of their own heart

Behold, I am against them that prophesy false dreams, saith the LORD, and do tell them, and cause my people to err by their lies, and by their lightness; yet I sent them not, nor commanded them: therefore they shall not profit this people at all, saith the LORD.
