What does the Bible say about false prophets and their dreams?

The Bible clearly warns about false prophets who misuse dreams as a means to propagate lies and lead others away from the authority of God's Word. In Jude 8-10, these individuals are labeled as 'filthy dreamers' who defile the flesh and despise dominion. They create a false narrative that undermines legitimate authority established by God. Such conduct is connected to an ancient warning in Deuteronomy 13, where the Lord instructs His people to reject any prophet or dreamer who calls them to serve other gods. Instead of accepting God’s authority through Scripture, these false prophets promote self-authority, writing their own moral codes and leading many astray.
