The oldest known dream interpretation text is the Assyrian Dream Book, dating to around 670 BCE, though the tradition it records is far older. In ancient Mesopotamia, dreams were understood as direct communications from the gods β not metaphors or psychological signals, but literal messages that required trained specialists to decode.
These specialists, called "dream priests," held significant social status. Kings would consult them before major decisions. The Epic of Gilgamesh, one of the oldest written stories in human history, features dream interpretation as a central plot device β Gilgamesh's mother interprets his dreams as prophecies about the arrival of his companion Enkidu.
The Mesopotamian approach was largely omen-based: specific dream images were catalogued alongside their predicted outcomes. Dreaming of certain animals, objects, or people had fixed meanings that didn't vary based on the dreamer's personal circumstances. This differs significantly from modern psychological approaches, which treat the same symbol differently depending on who is dreaming it.
