A TRADITION
The modern sleep-science view
What contemporary research can and can't say about why we dream.
Why we dream, as far as science knows
Modern sleep science studies dreaming empirically. Most vivid dreaming occurs during REM sleep, and researchers have proposed that dreams may help with memory consolidation, emotional processing, and threat rehearsal — though no single theory is settled.
Common dreams, common threads
Studies find that certain dreams — being chased, falling, losing teeth, being unprepared — recur across populations. Rather than pointing to fixed meanings, this suggests they tap shared human concerns about safety, change, and competence.
How this sits beside the traditions
We hold the scientific and the traditional views side by side without collapsing one into the other. Science explains mechanism; the traditions offer language for reflection. This dictionary is for cultural interest and self-reflection, not medical guidance.
