Why Do We Dream?

Dreams occur during REM (Rapid Eye Movement) sleep and serve multiple purposes. Scientists believe dreams help process emotions, consolidate memories, and work through complex problems. During REM sleep, your brain is almost as active as when you're awake, creating vivid narratives from your experiences, fears, and desires. Some theories suggest dreams act as a 'mental rehearsal' for real-life situations, helping us prepare for challenges. While we spend about 6 years of our lives dreaming, the exact purpose remains one of neuroscience's fascinating mysteries. Recent research indicates that dreaming may also help clear out unnecessary neural connections, making room for new learning.
