Contrary to the older view that dreaming is confined to REM sleep, current evidence shows dreams can occur during sleep entry, mid-sleep, and sleep exit across all phases.

Using blocks to visualize the architecture of sleep, Dr. Jandial traces the progression from sleep entry (N1) through progressively deeper phases (N2, N3) and into REM — Rapid Eye Movement sleep, when eyes move rapidly behind closed lids and the brain enters its most dream-fertile mode. The old scientific consensus held that meaningful dreaming was confined to REM. The newer picture, built from sleep labs where people are woken at random intervals and asked to report, is more expansive: dreams can occur at any phase of sleep, including right at the edges of falling asleep and waking up. This is both scientifically important and practically useful — it means the transitional moments at sleep entry and exit are fertile ground for dream capture and dream priming, not just the deep-night REM phases.
The widely cited ego-depletion model — the idea that willpower is a finite resource that gets depleted — failed to replicate in follow-up studies.
Humans are estimated to have 5,000–7,000 thoughts per day, yet can recall essentially none of them afterward, highlighting why in-the-moment emotional tracking matters.
A large Harvard study found that a wandering mind is an unhappy mind — people report greater happiness when their attention is tethered to the present, even if the task is unpleasant.
A key study finding that we have a 'credit card's worth of plastic' in our bodies was likely skewed because researchers used nitrile gloves that shed plastic particles onto the microplastic detector.
Emotionally sensitive people have a hyperactive amygdala, an underactive prefrontal cortex, and a frayed connection between the two — making emotional regulation structurally harder.
Rejection sensitivity can be observed as early as age 2 or 3, suggesting it has strong developmental and likely genetic roots.
A Yale study found that non-judgmental observation of emotions — without rushing to resolve them — reduces activation in the brain, making it a powerful regulation tool.
Dan Gilbert's research found that the psychological immune system — the brain's ability to justify and find satisfaction in choices — activates most powerfully when a decision is perceived as irreversible.
Barry Schwartz's research found that maximizers — people who try to optimize every decision — tend to achieve objectively better outcomes but report lower happiness than satisficers who choose 'good enough.'
