The brain is an incredibly complex machine. Dreams are still a great mystery to man. But we regularly make progress in understanding them.
What happens when you dream ? Why does our brain start creating these scenarios and other events in our head? How does he choose what we want to see or what we need to see? So many questions about dreams to which we currently have no answers. Couldn’t we simply ask, during the dream , what exactly he dreams of?
Researchers have managed to communicate with people in a dream
According to researchers at Northwestern University, it may be possible. At least, that’s what this team is currently studying. Scientists act when the person is in the midst of a lucid dream, a dream in which the dreamer is aware that they are dreaming and where they can even control the dream to some extent. Researchers take the opportunity to ask questions of the dreamer and the dreamer responds via eye movements or muscle contractions.
Researchers found that dreamers could follow instructions, answer closed questions – which expect a yes or no answer – solve simple mathematical equations, and even differentiate certain tactile or auditory stimuli. According to Karen Konkoly, a cognitive neuroscientist at Northwestern University, “this shows that it is possible to correctly perceive external stimuli and perform the operations necessary to respond to them while remaining asleep.”
This could pave the way for new therapies
That being said, this study is not a resounding success. Indeed, of 158 two-way communication attempts during REM sleep, only 18.4% produced correct answers, but Ken Paller, director of the Cognitive Neuroscience Program at Northwestern University, says that is enough.
In his own words, “We only needed adequate responses from certain patients to demonstrate that such two-way communication is possible, which was our first conclusion. We have shown that this can even occur in individuals with very little experience in lucid dreaming. ” With these findings, their method could be used to further study dreams and other cognitive activities like memory. One could even imagine future therapies for nightmares, spiritual development or problem solving.
