What do we all say when we talk about Dreams?

Dreaming can occur at any stage of sleep, whether it's rapid eye movement sleep (REM) or non-rapid eye movement sleep (non-REM), but it occurs more frequently in non-fast eye movement sleep. Since all body movements, except eye movement, are temporarily paralysed during REM sleep, Barrett believes that dream words are associated with the failure of nerve signals that inhibit movement.

On the other hand, because non-fast eye movement sleep does not cause paralysis of the body's movements, Barrett believes that dreaming during this sleep phase is caused by "partial awakening" in areas of the brain involved in speech, which can be captured by electrodes attached to the scalp, known as electroencephalogram EEG. "At this point, people don't show ethnical signals in full waking mode, but it's possible that in a very small area of the brain, or in a very short period of time, the recorded electrical signals will look a bit like waking e-brains, rather than like normal non-fast eye movements," she said.

This theory is also linked to its findings, with studies finding that sleep disorders in general may be caused by abnormal neural activity in the "wake-like state" produced by a particular brain region during sleep, which can lead to awake behavior during sleep. however, little is known about why brain activity becomes more alike when awake, and what threshold conditions drive people to say dreams.

The content of a person's dream words depends largely on what stage of sleep he is in. barrett describes the gradual development of dream words in the four stages of non-fast eye movement sleep: from the vague sounds and simple words in the fourth stage (the deepest sleep), to the ability to utter simple phrases in the third stage, and finally to form complete sentences in the second phase.

Sleep cycles typically include non-fast eye movement sleep and rapid eye movement sleep. according to the frequency characteristics of the electroencephalogram, non-rapid eye movement sleep can be divided into four stages, from the first stage to the fourth stage, the degree of sleep gradually deepens, the frequency of brain waves gradually decreases. the rapid eye movement period of the brain is high frequency low amplitude, the vast majority of dreams occur at this stage.

But the magic happens during fast eye movement sleep. "during fast eye movement sleep, you can hear anything you can imagine," barrett says. she often hears dreamers monologues or conversations with someone in their dreams (and stays for the right amount of time to wait for an answer). even less common, people even "play" both sides of the conversation in their dreams. "they tell jokes, laugh, cry, sing - whatever you can say when you're awake, they can say it in a dream, " barrett adds, adding that, in general, what you say in a dream is not as logical as what you say when you're awake.

However, although the content of the dream words may sound odd, they are still grammatically correct. in the only recent study on the linguistic characteristics of dream words, researchers analyzed the languages of 232 french dream speakers and found that the sentences were as complex as syntax when awake and followed grammatical rules.

As for what people say in their dreams, this study shows that the words most often mentioned in sleep are "no" or variations. dirty words are also often used, and they occur much more frequently at night than during the day. more general verbal abuse, such as insults and condemnations, is surprisingly common, far outnumbering polite language. the authors of the paper believe that a large number of negative connotations in dream words may reflect negative psychological content of dreams in the brain during sleep.

But the relationship between dream talking and dreaming is not yet clear. in the 1870s, studies found that there was a correlation most of the time between what people said in their dreams and what they could remember, but the correlation was not always obvious.

"It seems that the parts of dreams that people can remember don't seem to agree with what they say in their dreams, " barrett said. " ”

Dreamers can't completely rule out saying embarrassing things, but the good news is that the content of dreams can't be evidence against them in court. Mark Pressman is a 40-year veteran clinical sleep researcher who is now a forensic sleep specialist. Dream words, he said, had occasionally been allowed as evidence in the past, but had recently been excluded from the courtroom. That should be the case, Presman argues -- because science has shown that dream talk does not conform to federal rules defining evidence. It is hearsay evidence and cannotbe accepted in court. ”

In 2018, presman has collaborated with others on an article criticizing the use of outdated, unscientific dream words in court cases. but from a scientific point of view, even the latest research on dream words is becoming obsolete -- most of the work was published before the 1880s. barrett and his colleagues are slowly changing that through more research. at the same time, we may be able to say that a new frontier has emerged - dreaming with theeyes - in lucid dreams, where we can answer questions simply by eye movement.

Lucid dream is a dream made when conscious, also known as a qingming dream. Lucid dreaming is not the same as daydreaming, which is when the dreamer remains conscious in his sleep state, and daydreaming is when the dreamer meditates or fantasizes in his awake state rather than in his sleep state.
