DAVID NIELD19 FEBRUARY 2021
Scientists have identified a new phenomenon they describe as "interactive dreaming", where people experiencing deep sleep and lucid dreams are able to follow instructions, answer simple yes-or-no questions, and even solve basic mathematics problems.
As well as adding a whole new level of understanding to what happens to our brains when we're dreaming, the new study could eventually teach us how to train our dreams to help us towards a particular goal, for example, or to treat a particular mental health problem.
There's plenty about the psychology of sleep that remains a mystery, including the rapid eye movement (REM) stage where dreams usually occur. Being able to get responses from sleepers in real time, rather than relying on reports afterwards, could be hugely useful.
"We found that individuals in REM sleep can interact with an experimenter and engage in real-time communication," says psychologist Ken Paller from Northwestern University. "We also showed that dreamers are capable of comprehending questions, engaging in working-memory operations, and producing answers.

One of the researchers watching brain signals from a sleeping participant in the lab. Researchers are working to expand and refine two-way communications with sleeping people so more complex conversations may one day be possible.

Four independent experiments across the globe have found that it's possible to establish two-way communications with people in the weird, hallucinatory state of lucid dreaming, opening up a new field of real-time "interactive dreaming" research.
This is a big deal for scientists trying to work out what the heck is going on as we sleep, because typically they've had to rely on the fragmented, fading scraps of memory people have once they've woken up. "Our experimental goal is akin to finding a way to talk with an astronaut who is on another world," reads the introduction of a combined study between four separate groups in France, Germany, the Netherlands and the USA.
Each group set out to test its own techniques on how to "interview" people without waking them up, using the bizarre phenomenon of lucid dreaming as a doorway into the dream world. During regular dreams, we typically have no idea that we're dreaming, simply accepting the strange situations we're placed in without critical judgement. Lucid dreaming, a "notoriously rare phenomenon," is a state where the sleeper is aware that they're dreaming, and sometimes capable of steering their experience.
The researchers took one group of experienced lucid dreamers, another of regular folk that they had trained in the art of lucid dreaming, and one patient with narcolepsy who frequently drifted in and out of lucid dream states and found they were able to have two-way exchanges with members of all three groups.
In all the tests, the scientists verified that each subject was in a state of REM sleep, using "standard polysomnographic methods." Facial and eye movements were chosen as the means by which the dreamers could "talk back" to the researchers from the dream world, and the subjects were trained in specific ways of communicating. Some, for example, were trained to move their eyes left to right three times (LRLRLR) in response to an audio cue if they wanted to communicate that they were in the lucid dream state. None were trained with the specific questions they'd be asked when they were asleep.

(108,977 posts)if I heard someone talking to me, even in REM sleep, that would instantly wake me up.
I've spent too many years as a mother, I think, to not wake up to the sound of a human voice.

(42,552 posts)Four days later, with the investigation stalled, Captain Picard decides that the time has come to move on, but the crew find the ship also stalled like the Brattain. Data discovers that both ships are trapped in a spatial phenomenon known as a "Tyken's Rift", and they can only escape through the force of a tremendous explosion. However, as they work at determining how to create this explosion, the crew starts becoming irritable and experiences hallucinations. Dr. Crusher realizes that everyone but Troi has failed to achieve R.E.M. sleep since entering the rift, leading to their current state. As violence begins to erupt around the ship, Picard assigns Data, who does not sleep or dream and is therefore unaffected, as acting Captain.
Data eventually attempts to use a pulse from the deflector aimed at the center of the rift to create the explosion, but this fails to produce any effect. As Data looks for other solutions with Troi, Troi gets an idea that her dreams of "eyes in the dark, one moon circling" is a description of a hydrogen atom. Data and Troi work out that there must be another ship from a psychic race trapped on the other side of the rift who is aware of their presence but looking for hydrogen to create an explosion. Troi goes to sleep to contact the other species through the dream, while Data vents hydrogen into the rift. An explosion soon occurs, and both the Enterprise and the alien ship are freed. As the crew recovers, Data returns the ship to Picard, but not before ordering everyone to get some sleep.

The exchange between my dream self and conscious self is too valuable to meddle with.
If I want to communicate with another person, I'll do so when awake.
TY.
Caveat: Unless it is possible to alter the unconscious of violent criminals. That's a big IF & somewhat dangerous, I would think.

(14,015 posts)An unfettered, natural dream I had regarding my situation at a romantic crossroads clarified matters for me in a manner that prevented me from being related by marriage to Stephen LaBerge, Ph.D., noted expert in the field of lucid dreaming.
I'd never put it together in quite that way until just now.

(833 posts)that any practical use of this procedure, even on criminals, will only be a step toward broader use. Unfortunately, it will happen, anyway. Science has made it possible, so we won't be able to resist it. Take the A-bomb as an example.
Maybe it is the cynic in me (hell, that is exactly what it is), but this kind of thing has dangers and uses that we are not even aware of yet. I know I read way too much science fiction in my life, but still...

(5,126 posts)and therefore never figures it into their equation when it comes to potential damage... that trend has always been an issue with progress. I want progress, but when it comes like a boulder rolling down Mt. Everest, we may need to slow down a bit and ponder all implications, no matter how wild they may appear at first.

(444 posts)My ex wife used to talk in her sleep. (A lot) She would be having a conversation with someone, so I just started talking to her back and forth, as if I was the person she was conversing with. I was able to keep the conversation going, sometimes for over five minutes.
At some point, she would wake up and she would get superbly pissed that I was doing that with her.
One night I figured out that the person she was conversing with was a guy with whom she was having an affair, based on her sleep talking. I also figured out, from the conversation, who the person was that she was screwing....
And that is why she's my ex.........along with one of MY best friends......
