Scientists have found that sleeping people can talk

We dream every day, so wetake them for granted. At the same time, scientists do not know much about dreams, and science has not yet sufficiently determined their purpose. Interestingly, some people do not remember what they saw in a dream and do not attach any importance to dreams. Others, on the contrary, are attentive to their dreams, trying to analyze and interpret them in any possible way. Recently, a team of scientists from France, Holland, the United States and Germany conducted an extremely interesting study to obtain more accurate data on dreams. In the course of the study, the researchers asked the subjects questions while they were in a state known as lucid dreaming - a type of dreaming in which the person who is dreaming is aware that he is asleep. The results showed that in the dream, the subjects recognized questions from the outside world and even answered them. Note that the article published in the journal Current Biology is somewhat unusual and includes four independently conducted experiments with different methods to achieve this goal.

Scientists have discovered that you can communicate with people in a dream

Why do we dream

The question of why we see dreams tookphilosophers and scientists for millennia. But despite the scientific achievements of recent years, scientists still do not have a clear answer to the question of why we sleep and dream. Some of the best-known theories hold that the function of dreams is to consolidate memories, process emotions, express our deepest desires, and practice confronting potential dangers.

Other researchers suggest that we seedreams are due to a combination of these and other reasons and do not adhere to a single theory. In addition, while many scientists believe that dreams are essential for mental, emotional, and physical well-being, some believe that dreams do not serve any real purpose at all.

A deeper understanding of such a complex and vital process as sleep will help scientists understand its impact on physiological and psychological health.

But despite the many mysteries, scientists still know something about dreams: in total sleep lasts about two hours all night, regardless of whether you remember afterwaking up what you dreamed or not. Interestingly, the most vivid dreams are observed during REM sleep (from the English rapid eye movement, REM), these are the dreams we most likely remember when we wake up. Since we have colorful and vivid dreams during the REM phase, it may not be obvious that real-time communication with other people who are awake is possible.

We also dream during other phases of sleep (non-REM), but these dreams are known to be less remembered and have a more mundane content.

Lucid dreaming

Although lucid dreaming goes back at leastAt least, to the writings of Aristotle, this term was introduced in 1913 by the Dutch psychiatrist Frederick van Eden, who identified seven types of dreams. He believed that lucid dreaming "is the most interesting and worthy of the most careful observation and study." According to Big Think, the link between lucid dreaming and rapid eye movement (REM) phase was first established in 1975 by Keith Hearn.

In 2009, the scientific journal Sleep publishedlucid dreaming study conducted by scientists from the neurological clinic at the University of Frankfurt. The results obtained showed that the physiological picture of lucid dreams is more reminiscent of the picture of wakefulness, rather than ordinary sleep. Since there is a rather large difference between real wakefulness and lucid dream, it was decided in scientific circles to consider lucid dreaming as an intermediate state.

It turns out that being in a lucid dream, you can talk with others and answer questions.

Recently, in a study published in the journal Current Biology, researchers found that during REM sleep, subjects could actually answer questions and engage in real-time dialogue... The experiment involved 36 volunteers who answered a total of 158 questions. Response methods ranged from smiling and frowning to eye movements.

Four experiments were carried out in differentuniversities. The first at the University of Osnabrück in Germany, the second at the Radbud University of Rotterdam in the Netherlands, the third at the Sorbonne University in France and the fourth at the Northwestern University in the United States.

As explained in a press release of the study, one ofAuthors of the scientific work Karen Conkloli, the teams decided to combine their results, as they assumed that the combination of results from four separate laboratories using different approaches is the most convincing evidence of the reality of this two-way communication phenomenon.

The observations and stories of the participants in the experiments confirmed that the volunteers heard or saw the questions and tried to answer them both in dreams and in reality.

Overall, the researchers found that humans candistinguish between different sensory stimuli, understand instructions, perform simple math calculations, and answer yes or no questions in your sleep. All subjects answered the scientists' questions by contracting their facial muscles or moving their eyes. This new type of communication is now called "Interactive dream"... The researchers hope that this communication method will help to learn more about the characteristics of human sleep.
