The Bible presents dreams as a way God communicates with people, often delivering messages, warnings, revelations, or guidance. Dreams recorded in both the Old and New Testaments are typically initiated by God, not by the individual experiencing them. For instance, God spoke through dreams to figures like Abraham, Jacob, Joseph, Daniel, and New Testament figures such as Joseph (Mary's husband) and the apostles Peter and Paul. These dreams can include divine promises, prophetic visions, or instructions for action. Importantly, the Bible emphasizes that dreams serve as a medium for God to reveal His will or future events, and their interpretation is often a gift from God (Genesis 28, Matthew 1-2, Daniel 2, Acts 9, 18).

Several scriptures highlight that in the last days, God's Spirit will pour out so that people will prophesy, see visions, and dream dreams, indicating the ongoing spiritual significance of dreams (Joel 2:28). Biblical examples include Jacob's dream of a ladder reaching to heaven, Daniel interpreting King Nebuchadnezzar’s dreams, and Joseph receiving divine direction concerning Jesus' birth and safety. Additionally, dreams in the Bible are always portrayed as meaningful and often require God's revelation for proper understanding. Thus, the Bible teaches that dreams can be a divine tool for communication, guidance, prophecy, and encouragement, always subject to God's purpose and interpretation.
