#1 Brain Surgeon: What Your Dreams Are Trying to Tell You About Yourself

KEYPOINTS

• 01

  Dreaming takes up about a third of your life, not just a few minutes a night

  Dr. Rahul Jandial, a neurosurgeon, cancer surgeon and neuroscientist, says newer measurements show dreams can happen in any stage of sleep, including as you fall asleep and as you wake up. That is why he now estimates a third of our lives is spent dreaming. His framing: sleep is rest for the body, but the brain is 'on fire', with blood flowing and electricity firing, so it is not an idle screen-saver.

• 02

  Everybody dreams; 'I don't dream' really means 'I don't remember'

  When the show polled its audience, 26% said they don't dream or don't remember dreams. Jandial says recall can be cultivated. Editors at his publisher reported remembering more dreams while working on his book, almost everyone remembers childhood nightmares, and after caring for some 15,000 patients he says dreams tend to return near the end of life.

• 03

  At night the brain's 'CEO' quiets down and the imagination and emotion systems take over

  By day the executive network runs the show: getting on the subway, getting the kids to school. In dreaming, brain scans show that network dampened while the imagination network (loose, creative dot-connecting he calls 'creative ideation') and the limbic system (amygdala, hypothalamus and other emotional structures) are more active. Total brain activity is about the same as when you're awake. It's just a different mix.

• 04

  Dreams may keep unused parts of the mind 'warm'

  Jandial's view, which he presents as his belief backed by some scan data, is that emotion, creativity, sexuality and imagination get a kind of high-intensity training at night. Without that rehearsal those capacities might be less available when we face challenges during the day. When you dream of running, the same motor neurons fire as in real running. The signal just stops at the spinal cord, which may make dreams a true form of rehearsal.

• 05

  The brain cycles through N1, N2, N3 and REM, and REM is where vivid dreaming peaks

  Sleep entry is N1, followed by deeper N2 and N3. Scientists used to believe dreams happened mostly in REM (rapid eye movement) sleep. Now they know dreaming happens across stages. REM timing is the most fixed, and the late-night REM periods give the most vivid, best-remembered dreams, which matters for the lucid-dreaming technique below.

• 06

  A nightmare is a specific thing, and a flare of nightmares can be a mental-health warning sign

  By his definition, a nightmare isn't just a bad dream. It is terrifying and it wakes you up. Everyone has them. When people who think they're coping well suddenly get more nightmares, he treats it like a headache or pain: a vital sign that something unprocessed is going on and a prompt to ask whether you're really living well. He adds that nightmares are also linked to more serious risks, including suicide, so persistent ones deserve attention.

• 07

  Many common dreams seem built into the brain, but their meaning is often unknowable

  Falling, flying and being chased show up in half to two-thirds of dream reports, across cultures and centuries, including before airplanes existed. Jandial takes that consistency as evidence the brain generates these dreams partly on autopilot. He's openly humble here. Asked why people dream of teeth falling out, he says 'I don't know,' noting only that it correlates a bit with teeth grinding.

• 08

  Some dreams are obvious and some are best treated as prompts for reflection

  He describes several categories of dreams, starting with the 'obvious' one, like showing up naked to a talk you're anxious about. He doesn't decode symbols. He suggests that a dream caught in the morning offers another view of your own experiences, one a therapist can't have because it's 'in my head.' He calls it a free wellness tool and a kind of 'nocturnal therapist,' while admitting that PTSD dreams can keep trauma alive.

• 09

  The minutes when you're falling asleep and waking up are a creative window

  Those 5–15 minutes carry electrical signatures of both waking and sleep. Jandial says he has used the waking window for decades as an idea generator, staying in bed without grabbing his phone. Artists have long described the same thing. The recall he means is subtle: a lingering emotion, an image, a different way of thinking about a problem, not a crisp replay.
