POPSClues to Why We Dream at All ... In a recent paper in Psychological Bulletin, Dr. Nielsen and Dr. Levin proposed that dreaming served to create what they call “fear extinction memories,” the brain’s way of scrambling, detoxifying and finally discarding old fearful memories, the better to move on and make synaptic space for any novel threats that may show up at the door. “The brain learns quickly what to be afraid of,” Dr. Nielsen said. “But if there isn’t a check on the process, we’d fear things in adulthood we feared in childhood.” Ordinary bad dreams rarely recapitulate unpleasant events from real life but instead cannibalize them for props and spare parts, and through that reinvention, Dr. Nielsen explained, the fears are defanged. “A bad dream that doesn’t lead to awakening is successful in dealing with intense emotion,” he said. “It’s disturbing, but there is some kind of resolution to the extent we don’t wake up.” ...

Instead of merely imagining that you’re grasping a nanotool with virtual fingers, you could learn to pilot it like a minuscule spaceship—only with your mind. And if that device had any sensors, you might be able to process the data as though it were a tiny camera.
