Researchers discover that sleeping people can answer questions and do sums
What happens in our brain when we fall asleep? For the most part, it remains a mystery.
We know that when we sleep, our brain carries out a certain activity. For that reason we dream and remember some of these dreams. Now four different groups of researchers they have checked what during lucid dreams, we can even communicate with the outside.
Full asleep, it is possible to answer questions using muscle movements, and even perform arithmetic operations.
In a study led by Northwestern University Professor Karen Konkoly, 36 people were connected to EEGs during sleep. It was specifically studied the REM phase, which is when the eyes move compulsively, and have the most lucid dreams.
During this phase, the subjects were stimulated with external actions such as spoken language, flashlights or physical contact. In addition, certain eye or muscle movements were agreed with the patients for an answer “Yes”, and a different one for a “No”.
During the dream they were asked questions like, “Do you speak Spanish?“Or the flashlight was turned on a number of times and asked to count.
In 47% of the tests, subjects answered at least one or more of these questions correctly, including counting. In other cases they failed, but they had understood the question.
It is also very interesting to know what the subjects of the experiment remembered. Some had no recollection of the questions, even though they had been answered well. Others remembered a voice ringing over a dream, and in some cases they heard the voice coming out of objects that were in their dream, like a radio.
“These repeated observations of interactive dreams, documented by four independent laboratory groups, demonstrate that the cognitive characteristics of dreams can be interrogated in real time.“, the researchers write in the results of the study, which comes to us via Science Alert.
“This relatively unexplored channel of communication may allow for a variety of practical applications and a new strategy for the empirical exploration of dreams.“, the document continues. For example, look for the origin of a problem, or treat a mental illness.
