Negative Dreams Are More Common Than Positive Ones
For some reason, we spend most of the night dreaming of negative dreams instead of positive ones. What’s the point in going to bed if we’re just going to have a fitful sleep? It’s because most of us have selective memory for intense, negative emotions, like sadness and fear. That being said, scientists have found that nightmares are good for you. According to Elemental, bad dreams could help reduce anxiety around real-life situations by acting as emotional dress rehearsals. Deirdre Barrett, Ph.D., a professor at Harvard claims that nightmares are an instinctive mechanism, that helps keep us on guard, even if we don’t have to worry as much about the same things our ancestors had to.
