Illustration: Angelica Alzona/GizmodoGiz AsksGiz AsksIn this Gizmodo series, we ask questions about everything and get the answer from a variety of experts.People say other peoples dreams are uninteresting, however what if the issue is technology? As a sense-conveying device, human speech is substandard, prone to gaps, stutters and falsifications, intentional or otherwise. If you could just actually show someone your dreams– suck them out of your skull and toss them onto the nearest screen– people may not roll their eyes when you tried to talk about them. Dream-movies have actually naturally been sci-fi fodder forever, but with numerous sci-fi staples verging on (or currently present in) reality, its worth wondering if were any closer to experiencing them. For this weeks Giz Asks, we connected to a number of experts to find out.Susana Martinez-CondeProfessor of Ophthalmology, Neurology, and Physiology & & Pharmacology, whose research bridges perceptual, oculomotor, and cognitive neuroscienceThere is no theoretical barrier to the possibility of accessing the contents of somebodys dream, and reading it out, and supplying information– emotional and visual material. Our dreams are neural activity in our brain; theres nothing special about them that doesnt affect every other psychological or perceptual experience we have in our waking lives. There is no specific circuitry or brain area that is activated throughout dreams however not in waking life.The huge caution is not the technology, but the reality that we still do not truly understand the neural code; we still do not know how conscious experience is encoded in the brain. The limits that make it impossible to share dreams today are the very same ones that make it difficult to say, download our consciousnesses onto a computer. It doesnt matter how quick technology progresses if we still do not actually understand the underlying neurophysiology. We still cant really decode experience. There are theories, but essentially we do not have agreement. Theres still substantial debate in the field about whether, state, the prefrontal cortex is critical for mindful experience. Were truly far behind– I think were talking about decades here, instead of years.But one day, if we do comprehend whats happening with the biology, and the innovation exists, theres no factor why we could not download our awareness onto a computer and live permanently– or, at the same time, share our dreams.”It doesnt matter how fast technology advances if we still dont really understand the underlying neurophysiology. We still cant actually decode experience.”Robert StickgoldProfessor, Psychiatry, Harvard Medical School, whose research study concentrates on sleep”Ever” is a really long time, but I think the response, at least for the life time of anyone visiting your website is, “Nah, not an opportunity!” Consider it– its practically impossible to share your ideas with somebody else verbally. As quickly as you begin, twenty new threads open up, and you have to pick just one. Theyre all there as part of your “ideas.” The best theyve had the ability to finish with completely awake people is put them in an fMRI scanner and figure out whether theyre taking a look at a face or a tool.On a more philosophical level, your thought, and your dreams, are constantly embedded in your general memory networks and life experiences. You cant “stroll in somebody elses shoes” by simply putting them on and treking on down to the mall.G/ O Media may get a commission”The best theyve been able to make with totally awake people is put them in an fMRI scanner and figure out whether theyre taking a look at a tool or a face.”Adam Haar HorowitzResearch assistant at the MIT Media Lab, whose work concentrates on brain scienceLike so much of science, the concern is a door to more doors. To share dreams we need to first specify them, draw some kind of limit around the dream– is it the visuals that specify the dream, is it sight we wish to share? If so, does a co-occurring picture of my mom in both of our minds satisfy the concept of a shared dream? I dont think so. Dreams are an amalgam of memory, theyre internal explorations of our networks of significance, theyre concepts always embedded in individual context. So the very same sensory stimulus in two minds may be a totally various experience. That being stated, we might ask if were ever viewing the very same movie, even while awake and sharing a sofa … philosophically its an unpleasant questionPractically, its less messy. There have been strides already at translating the visuals from a dream using brain imaging. Others have actually shown we can interact from within a lucid dream, using eye motions to interact across states of consciousness. And our work at Fluid Interfaces has shown we can incubate particular themes in dreams. On the surface area level, we are closing the space in between the personal area of the dreamscape and the outside observer. However I think that gap stays a type of Zenos paradox, since experience is always going to exist, pestering scientists even as we develop unbiased tools to capture, observe and recreate the dream. We can not share a whole dream without sharing a whole self. “To share dreams we need to first specify them, draw some type of border around the dream– is it the visuals that define the dream, is it sight we desire to share? If so, does a co-occurring image of my mother in both of our minds satisfy the idea of a shared dream?”T W C StonehamProfessor, Philosophy, University of York, whose research study concentrates on dreams, to name a few thingsR A DaviesResearch Associate, Philosophy, University of YorkBesides the harmless sense in which we interact our dreams, there are at least 2 interesting senses of dream-sharing: to have the very same dream (co-dreaming); and to see anothers dream, possibly through sophisticated innovation (dream-scanning). Examples of dream-sharing can be discovered in some contemporary African cultures, where one can dream for another person, and even triangulate (in dreams that relate messages from one celebration, through the dreamer, to a third). They likewise appear in ancient civilizations (Mesopotamia, Egypt, and Greece), including cases in which the exact same crucial dreams would take place in both client and priest on the same night (symptoma). On the common view in modern Western cultures, dream-sharing in these methods seems difficult, disallowing coincidence, dream-scanning, or tip. On that view, dreaming is an essentially private (sleeping) experience that can just presently be shared through (waking) communication: the experience itself occurs in isolation.Our research recommends that the prevalent Western view of dreaming is wrong. It does not easily discuss familiar sleep phenomena such as pre-cognitive (alarm-clock) dreams; the incorporation of low-level perception and interoception into dream content; and even how typical foods can cause bad dreams. Rather, we think dreams are built from a variety of sources– social and cultural effects, bodily feelings, and understanding– mainly as one awakens. On this alternative view, there is no fundamentally private experience behind our dream reports.If we are right, dream-scanning would not reveal much. We forecast that info one might acquire from scanning the brains of sleeping individuals will only correlate extremely loosely with their dream reports since what people report dreaming is affected by a lot of other elements, such as cultural norms and social expectations.There is wish for the other sense of dream-sharing, though. In principle, to start a similar dream in more than someone one might try to induce the same physiological and environmental changes in those persons while they sleep. Differences in age, health, diet plan, social aspects and cultural associations might still lead to differences in dream material, so one would have to select ones topics carefully. “There is hope for the other sense of dream-sharing. In principle, to initiate a similar dream in more than a single person one may try to cause the same physiological and ecological changes in those persons while they sleep.”Do you have a burning question for Giz Asks?
