Does someone speak a different language in their sleep?

Learning languages ​​in your sleep: and it still works!

"Movement sequences can be practiced and improved during sleep," says Daniel Erlacher, psychologist and sports scientist at the University of Bern. This happens in the lucid dream that goes through our minds at night. This is characterized by the fact that the sleeper is aware that they are dreaming.

Around half of all people experience a lucid dream at least once in their life, one in five even once a month or more often. The lucid dreams mainly occur in the REM sleep phase, when the brain is extremely active.

As part of a study, Daniel Erlacher asked test subjects to throw coins into a cup before going to bed in a lucid dream. Those who had practiced their skills in their sleep were aiming 40 percent better the next morning.

"Sometimes a lucid dream can be provoked on the first attempt."

The dream training also had an effect on athletes. For example, swimmers practiced newly learned styles in lucid dreams. In the next guard training they implemented this better. According to Erlacher's surveys, many lucid dreamers use this special state of consciousness primarily to experience crazy things, to meet certain people or for sexual interactions.

Lucid dreams can be provoked. To this end, the researcher recommends writing down dreams over a period of several weeks and identifying recurring elements. If you encounter this element again in a dream, in the best case you will be aware of it and recognize that you are dreaming.

The procedure becomes even more effective if you wake up after six hours of sleep, write down your dream and then go back to sleep. "Sometimes a lucid dream can be provoked on the first attempt, sometimes only after a few weeks," says Erlacher.
