What did you dream of last night? Do you remember? You probably had several dreams last night. But what are dreams? Why do we have them? What is their purpose?

When your body enters sleep, your brain undergoes several sleep cycles, four to fives times a night. Each cycle has its own purpose. The cycles range from drowsiness and light sleep to deep sleep. After deep sleep, the body (or more technically the brain) will enter a stage called Rapid Eye Movement, abbreviated REM sleep. It is during this REM stage where many of our dreams happen.
