The reason we dream has to do with the exact details of our planet's rotation combined with brain plasticity. If you had a planet that spun fast enough, like lots of planets do, if it spun fast enough that you were back in the light then you wouldn't need a 90 minute cycle of dreaming. We're not bot dreaming. It's like one of the reatest secrets of being a person,. In your leg ohno, this is what it is like. By the way, what happens within 30 minutes. This is a new idea for me and for a lot of people, the idea that dreaming is your brains defence against other parts of the brain taking over the visual cortex

In this episode we sit down with neuroscientist David Eagleman to learn how brains turn noise into signal, chaos into order, electrical spikes into meaning, and how new technology can expand subjective reality in ways never before possible.

In his new book, Livewired, Eagleman explores how brains come into the world "half baked" so they can create reality itself out of the inputs and experiences available. And now, thanks to that plug-and-play plasticity, with the latest tools, not only can we return senses to people who've lost them, but we can add to any brain senses we can't imagine.
