Why We Dream

Every night, our brains produce vivid stories that we call dreams, yet scientists still argue about why they happen. One popular theory suggests that dreaming helps us process emotions and store important memories. Another idea is that dreams are simply the by-product of a brain sorting through random signals while we sleep. Interestingly, people who are deprived of dream sleep often feel anxious and struggle to concentrate the next day. Modern brain scans have revealed that the regions linked to emotion are especially active during dreaming. Although the mystery is far from solved, most researchers agree that dreams serve a genuine purpose.
