Millionaires are jetting themselves into space and quantum computing lies around the corner. Yet, one of the most familiar and everyday aspects of human nature remains frustratingly tricky for scientists to study dreaming.
Theories abound, but the truth is we don't know much about why or how we dream. A major hurdle for scientists has been the fact that when people are dreaming, they're largely closed off from the world - at least that's been the assumption for a long while. So, researchers have resorted to asking people, upon awakening, what their mind was doing while they were sleeping, but that's a sketchy and unreliable approach.
“Memories of dreams can be missing some parts of dreams and can be distorted and incorrect, so if that's all we have to go on, then building a solid science of dreaming will be difficult, says Dr. Ken Paller, a psychologist and dream researcher at Northwestern University.
What would change the whole dream research landscape would be if there were some way to communicate and interact with someone while they were dreaming. It sounds far-fetched, like something out of the Christopher Nolan movie Inception, but in a significant breakthrough, that's exactly what an international team of researchers, led by Paller and Karen Konkoly, also at Northwestern University, managed to achieve. The work, which was published in the journal Current Biology in 2021, opens up the opportunities for scientific explorations of dreaming considerably, says Paller. “We now have more ways to learn about dreaming.
