Anger in dreams appears to have the same brain patterns as anger during wakefulness.
Scientists have discovered the brain activity that takes place when people are having angry dreams. Researchers found that people who had angry dreams had more activity in the alpha band in the right frontal cortex compared with the left—a pattern that is also found in the brains of people who are feeling anger during wakefulness.
Previous research has shown a specific neural marker is involved in emotional processing and anger-related states—the team wanted to find out if the same marker was found in the brains of people who were asleep. This pattern, known as the frontal alpha asymmetry , shows brain activity differs between the two frontal areas of the brain. Having evidence that this pattern relates to anger during sleep as well as wakefulness suggests it plays an important role in emotion processing. “Our findings show that anger in dreams has the same neural correlates as anger in wakefulness,” Sikka said. “This means that there seem to be shared brain processes for emotions across wakefulness and dreaming.
