Neuroscientists say that it's possible to engineer dreams.

“A powerful way to investigate memory consolidation during sleep utilizes acoustic stimulation to reactivate memories. In multiple studies, Targeted Memory Reactivation (TMR) using sounds associated with prior learning improved later memory, as in recalling locations where objects previously appeared.” (APAPsycNet, Targeted memory reactivation during sleep to strengthen memory for arbitrary pairings). 

Reseachers say that the purpose of dreams is to analyze things that happened during the daytime, or wake-up time. Friedrich August Kekulé von Stradonitz (1829 – 1896) was the chemist who uncovered. The structure of benzene. Saw in a dream. Where the snake. To bite its tail. When he woke up, Kekulé von Stradonitz realized that benzene is composed of a ring of carbon atoms. Same way. Compositors are seen. When a devil or angel. Who played some composition. In dreams. 

The most well-known case is the case of Giuseppe Tartini (1692–1770), who saw. The devil played violin in his dreams, and then Tartini created his Devil's Trill Sonata by following. The things that he saw in his dreams. 

Those things support the theory that dreams are made. For solving problems. The problem with the dream analysis is that people don’t remember their dreams. But. A technology called targeted memory reactivation (TMR). The TMR uses acoustic waves to activate memory blocks after sleep. The opposite system is TMD, targeted memory deactivator. TMD deactivates memory. 

That system might. Help people. To remember their dreams. The TMR technology has uncovered that.

 “Seventy-five percent of participants reported dreams that contained elements related to the unsolved puzzles. Problems that appeared in dreams were later solved at a much higher rate than those that did not (42% vs 17%)”. (ScitechDaily, Can You Engineer a Dream? Neuroscientists Say Yes – and It Boosts Creativity) 

"Tartini's Dream" by Louis-Léopold Boilly (1761-1845). Illustration of the legend behind Giuseppe Tartini's "Devil's Trill Sonata". Caption: TARTINI'S DREAM. It is said that Tartini saw in a dream the Devil who offered him his services, and that, at his command, he performed a sonata on the violin, which Tartini had never heard before and which he tried to recall upon waking. He then composed that singular sonata that is still known today under the name of the Devil's Sonata.” (Wikipedia, Devil's Trill Sonata)

That means that dreams are meant to solve problems. Or they can help to solve them. The ability to send information into human brains just before people sleep. It can make people more productive. Maybe, things like AI can someday turn our dreams into mode. That we could project them on the computer screen. Things. Like a brain-computer interface, BCI systems. Which can also. Connect human creativity. Into a model that the AI can control and use in its training. The problem is how to send the right information. Into the brain. In the right moment. 

The BCI can also read those things from the electrodes or brain implants. The ability to control dreams makes people more creative. Or, the problem is. How we remember things. That we saw while we sleep. “Targeted Memory Reactivation (TMR) is a noninvasive technique from cognitive neuroscience that allows researchers to selectively influence which recent memories are strengthened during sleep. The method is based on the brain’s natural process of consolidating memories while a person is resting”. (Biologyinsights, How Targeted Memory Reactivation Works and Its Uses)

Excitons and light form new quantum states.

“Physicists have long wondered what happens when a superfluid is cooled even further, and now, experiments in bilayer graphene hint at an unexpected answer. Credit: SciTechDaily.com” (ScitechDaily,Physicists Watch a Superfluid Freeze, Revealing a Strange New Quantum State of Matter)

The new form of quantum state of matter is found in bilayer graphene. The bilayer graphene is the thing. That can make a superfluid freeze or stop moving. This means that the graphene is covered by an icy superfluid. And that uncovered strange new quantum behavior in that thing. 

Researchers found an unexpected relationship. Between the density of the quasiparticles and the temperature. At high density, excitons behaved like a superfluid, but as their density decreased, they stopped moving and became insulators. When the temperature decreased, superfluidity returned. 

Those systems can revolutionize.  Quantum computing technology. The laser systems can be used to adjust that transition. 

This phenomenon can be used in superconducting miniature electronics. The ability to control insulation. And electric conductivity. It is an important thing for the gates and switches in the small superconducting microchips. 

The system can use a laser as a thermal pump. The laser can be used to adjust the energy flow in the graphene, so that it transports as much energy away from the fluid as possible. The superfluid is between those graphene layers. And that helps to control it.

“For all the theory and debate, the most famous candidate, helium, has not provided a definitive, natural example of a superfluid turning into a supersolid. Researchers have built supersolid-like systems in the atomic, molecular, and optical (AMO) sub-branch of physics, but those demonstrations typically rely on lasers and optical components to impose a repeating structure. This creates what is known as a periodic trap that encourages the fluid into a crystal-like pattern, a bit like Jello confined in an ice cube tray.” (ScitechDaily, Physicists Watch a Superfluid Freeze, Revealing a Strange New Quantum State of Matter)

“Controlling a superfluid in a 2D material is an exciting prospect—compared to helium, for example, excitons are thousands of times lighter, so they could potentially form quantum states such as superfluids and supersolids at much higher temperatures. The future of supersolids remains to be realized, but there is now solid evidence that 2D materials will help researchers understand this enigmatic quantum phase.” (ScitechDaily, Physicists Watch a Superfluid Freeze, Revealing a Strange New Quantum State of Matter)

Another thing is that. The light can. Have quantum ability. Which allows it. To control things. Like the magnetic field. The ability to force atoms at a very low temperature into straight lines can make it possible to create a situation where the magnetic fields travel through matter. This thing makes it possible.  To create quantum levitation, or the so-called Meissner effect. But the Meissner effect can also make it possible. 

To create systems that allow light to travel through the system. If there are no fields that can cause reflection. The system turns invisible to those wavelengths.  The reason for that is this. Without reflection, the energy or wave movements cannot reach the observer. That turns matter into a ghost. 

But the ability to control magnetism makes it possible. To create new fundamental material layers. Those layers can form the grooves by pulling the layer that reacts to the magnet down. And when those grooves are not necessary, the magnets can be shut down. 

There is also a possibility that the layer is made using tiny magnets. Those nano-scale magnets can be in the nanotubes. And. The system can turn them by using light. The ability to adjust their polarity. Makes it possible. To switch the polarity in the layer. 

These types of systems could also turn. The polarity of the magnets. Oppositely. This means that light turns those poles upside down. And that makes it possible to change the polarity of the layer.
