Why you keep having the same dream

For years, dreams of my teeth cracking, loosening or falling out plagued my sleep. Loved ones of mine have repeatedly dreamed of flying, rolling away in a self-operating car, or running late for school or work. These aren’t typical nightmares, which usually happen once. They’re some of the most common recurring dreams, which tend to lean negative and can take some work to overcome.（本段为发音精讲部分，具体语音讲解请微信关注【可可英语晨读公众号】）

“Recurring dreams are likelier to be about very profound life experiences or just very character logic issues that are kind of guaranteed to recur in waking life because they’re part of you rather than a one-time event,” said dream researcher Barrett, a lecturer of psychology in the department of psychiatry at Harvard Medical School.

Since our dreams typically don’t repeat themselves, all it takes is dreaming the same dream twice or more for it to be considered recurring, Barrett said. They’re more common in childhood, but can last into adulthood. And recurring dreams don’t always happen in close proximity to each other — they can pop up multiple times per month or years apart, Barrett said.

Recurring dreams might be the same every time, or they might just recycle the same types of scenarios or worries, experts said.
