No one knows exactly why we dream, but we do know that your thalamus, the structure in your brain which translates information from sense into memory, is active during REM, along with the amygdala, which houses fear and anger reactions, and the prefrontal cortex, which controls short-term memory.

The most popular theory of why we dream, stipulated by John Allen Hobson and Robert McCarley, argues that dreams are a byproduct of lower functions of the brain during REM sleep, like heart and blood pressure, translated by our higher functions, like memory and speech, into visual and auditory hallucinations, which were used by our ancestors to practice being conscious.
