Do Dreams Serve A Purpose?

In spite of their potent emotional force, dreams are merely the result of the random firing of neurons. It is only after we wake that the brain, seeking order, weaves the pieces together in search of some significance.

Dreaming of recent experience reflects the reactivation and consolidation of memory in the sleeping brain.

The purpose of dreaming is to determine what new information is useful and to help the brain make predictions about the future.
