'Dreams' in the Bible

When Saul inquired of the Lord, the Lord did not answer him, either by dreams or by Urim or by prophets.

Then Samuel said to Saul, “Why have you disturbed me by bringing me up?” And Saul answered, “I am greatly distressed; for the Philistines are waging war against me, and God has departed from me and no longer answers me, either through prophets or by dreams; therefore I have called you, that you may make known to me what I should do.”
