Dreams have fascinated humans for thousands of years. Ancient civilizations believed they were messages from the gods, while modern science sees them as a complex product of the sleeping brain. On average, a person spends nearly six years of their life dreaming, yet most of those moments are forgotten almost instantly. The mystery is not that we dream, but that our minds seem determined to erase them. Researchers now think this forgetfulness may actually serve an important purpose, helping the brain organize memories, regulate emotions, and prepare for another day.
