The nature of sleep will have to be radically revised, it can no longer be considered a state of some kind of isolation from the external environment for the sake of rest. This was confirmed by an experiment at the Northwestern University of Chicago (USA), in which 36 people with the skill of "lucid dreaming" took part. They not only took the given information inside their dream, but were also able to communicate with scientists from there without waking up.
The research is based on two factors. First, the human brain is initially able to transmit signals from the outside to the interior of sleep, to demonstrate them there in a metaphorical video. For example, if a blanket slips during sleep, a person may start dreaming about walking in the snow in the wind. Secondly, the lucid dream technique allows a person to understand that he is asleep and use this fact to control the plot of the dream. For example, he can purposefully transform into a fantasy hero and go to save the princess, if he tunes in to such a story in advance.
Before starting the experiment, the scientists agreed with the test subjects about code signals, according to which they had to pause sleep and perform arithmetic calculations. The response was transmitted through the rotation of the eyeballs or the contraction of the facial muscles. We chose the simplest tasks, such as "how much is 8 minus 6?", So that sleeping people would answer quickly, do not think and do not lose control over sleep.
Six out of 36 people heard the questions and gave the correct answers while sleeping. The very fact of such a two-way communication was confirmed, but its implementation turned out to be very difficult. For example, some participants woke up by moving their eyes too much or trying to blink. Therefore, it is not yet necessary to talk about the creation of an interactive dream technology, when it will be possible to learn in a dream or engage in creativity - but this is the beginning of a new direction in the science of human capabilities.
