More than 10 years have passed since the premiere of start In theaters, the film directed by Christopher Nolan starring Leonardo DiCaprio as Dom Cobb, enters other people’s dreams to interact with them and steal secrets from their subconscious, But Nolan’s script seems to be turning into reality.
Going from science fiction to science, a group of researchers have “conversations” with people that involve novel questions and math problems that they know they are dreaming Or as the studio calls them, the streamers.
According to the study, cited on the Science website, findings from four laboratories and 36 participants suggest that People can receive and process complex external information while they sleep,
As Benjamin Baird, a cognitive neuroscientist at the University of Wisconsin, expressed in this regard: “This work challenges fundamental definitions of sleep. Sleep is defined as a state in which the brain is shut down and unaware of the outside world.,
Lucid dreaming has been studied since the 1970s and was first mentioned by Aristotle. Although it is rare, the ability to recognize that you are in a dream, and even control some aspects of it, can be improved with training. Four independent teams in France, Germany, the Netherlands and the United States tried to go further.
researchers tried to establishing complex two-way communication during dreams, using speech and asking questions that the sleepers had never heard in their training,
They recruited 36 volunteers, including some experienced lucid dreamers and others who had never experienced lucid dreams before but recalled at least one dream per week.
First, the scientists trained participants to recognize when they were dreaming, explaining how lucid dreams work and demonstrating the cues (sounds, lights, or finger taps) that they were dreaming. Will present it while the watchers are sleeping. The idea was that these cues would signal to the participants that they were dreaming.
Nap sessions were scheduled at different times: some at night and some in the early morning. Each lab used a different method to communicate with the sleeper, from spoken questions to flashing lights. sleepers were asked to indicate that they had entered a lucid dream and Answer questions by moving your eyes and face in a specific way, for example, moving your eyes to the left three times,
As the participants fell asleep, the scientists monitored their brain activity, eye movements and facial muscle contractions – common indicators of REM (rapid eye movement sleep) sleep with electroencephalogram headsets equipped with electrodes.
Out of a total of 57 sleep sessions, Six people indicated that 15 of them had lucid dreams, In those tests, researchers asked dreamers simple yes-or-no questions or math problems, such as eight minus six. To answer, the dreamers used the signs they were taught before falling asleep.
Researchers asked lucid dreamers 158 questions, who answered 18.6% correctly, The streamers only answered 3.2% of the questions incorrectly, 17.7% of their answers were unclear, and 60.8% of the questions were left unanswered.
The researchers say these numbers show that communication, however difficult it may be, is possible: “This is a proof of concept. And the fact that different labs have used all these different methods to show that it’s possible to have this kind of two-way communication… makes it even stronger.,
