What happens to your brain when you’re dreaming

9 квіт. 2026 р.

We created this video in partnership with Unlikely Collaborators. Have you ever woken up after a dream and thought to yourself, “That made absolutely no sense”? According to modern neuroscience, there’s a reason why dreams feel so abstract and bizarre. Two sleep experts discuss. Subscribe to Big Think on YouTube ► https://www.youtube.com/channel/UCvQECJukTDE2i6aCoMnS-Vg?sub_confirmation=1 Every 90 minutes, our bodies go paralyzed while our brains become more active than during waking life. Sleep psychologist Dr. Shelby Harris and neuroscientist Dr. Patrick McNamara, Associate Professor of Neurology at Boston University, dig into one of the most fascinating mysteries in human biology: why we dream and what our brains are actually doing during REM sleep. They explore competing theories of what dreaming is for, McNamara makes a compelling case that REM sleep may have been a key driver of early human creativity, and both reflect on why reclaiming our reverence for the dream state could change the way we think and create.

Her work explores “technosignatures” — physical clues of advanced life, from satellite swarms to artificial light. As artificial intelligence accelerates here on Earth, Seager considers whether post-biological life might be what awaits us — and whether it already exists elsewhere in the cosmos. Our biggest challenge, she suggests, may be learning to see past the limits of our own imagination.

Toxic positivity is corrupting America | Kate Bowler

Subscribe to The Well on YouTube ► https://bit.ly/thewell-youtube Watch Bowler’s next interview ► Why pain doesn't need to teach you anything https://www.youtube.com/watch?v=9JlOgjf7Y_8 Toxic positivity has become a cultural system in America, says historian and professor Kate Bowler. She traces how optimism became an emotional mandate in American life: a belief that bright sides and silver linings can solve anything. But when positivity refuses pain, it stops being hopeful and becomes denial. Drawing on personal experience and cultural analysis, Bowler reveals how forced optimism erases nuance, stigmatizes grief, and leaves us unprepared for the parts of life that don’t resolve. Some things aren’t meant to be mastered — they just hurt. Naming that, she argues, is the first step toward something more honest, and more human.

Research into Mars, Venus, and the icy moons of Jupiter and Saturn has revealed complex molecules and liquid environments that could support life. Independent origins of life would imply that the galaxy is rich with living individuals, challenging long-held cultural, religious, and philosophical assumptions.

Your life needs more ‘existential grit.’ Here’s how to find it | Kate Bowler

Subscribe to The Well on YouTube ► https://bit.ly/thewell-youtube Watch Bowler’s next interview ► Why toxic positivity is making us miserable https://youtu.be/ebCqCPxZcV8 Joy is often mistaken for a stronger version of happiness. But historian and writer Kate Bowler argues that they are fundamentally different emotions. Happiness, she explains, depends on things going well. It’s cumulative, fragile, and easily undone. Joy, by contrast, can exist alongside pain, grief, and uncertainty. It doesn’t erase what’s broken — it helps hold it together. Drawing from psychology, faith traditions, and her own experience living with stage four cancer, Bowler explores why joy is less about ease and more about connection, openness, and love. It’s not a mood or an achievement, but a way of seeing reality clearly and still saying yes to life. Joy, she suggests, isn’t a bonus for the fortunate. It’s something that carries us when happiness no longer can.
