Researchers from Turku University monitored the brains of sleeping people and asked them to report the emotional content of their dreams.
The researchers claimed that people who had a certain configuration in their brainwaves were more likely to feel anger in their dreams.
This discovery could help scientists understand nightmares, which are often a side effect of sleep disorders, the researchers said.
Lead author Pilleriin Sikka said, "We found that people who showed greater brain activity of the alpha band in the right frontal cortex than in the case of left watch and REM sleep felt more angry. than dream.

"This neural signature is known as frontal alpha asymmetry (FAA)
The brain activity of the alpha band refers to brain waves with a frequency of 8 to 12 Hz, and they are particularly prevalent during the day before.
Alpha waves are thought to reflect the inhibition of the underlying brain areas.
More alpha waves in the right frontal region therefore indicate a lower activity in this region of the brain.
Sikka said, "Previous studies have shown that frontal alpha asymmetry is related to anger and self-regulation during the day before.
"Our research findings show that this asymmetric brain activity is also related to the anger felt in dreams."
