A new study has revealed that dreams are a gateway for grappling the inner turmoil human beings face in their lives.
The Daily Mail reported scientists have found that dreaming is essential to cope with emotional stress.
The team studied 35 healthy young adults, divided into two groups. All of them viewed 150 emotional images, twice and 12 hours apart, while an MRI scanner measured their brain activity.
Half of the participants viewed the images in the morning and again in the evening, staying awake between the two viewings. The remaining half viewed the images in the evening and again the next morning after a full night of sleep. Those who slept in between image viewings reported a significant decrease in their emotional reaction to the images.
The MRI scans showed that sleep caused a dramatic reduction in reactivity in the amygdala, a part of the brain that processes emotions.
