Dream statistics: how common is your dream?
Every figure below traces to published, peer-reviewed research
The short version
Being chased is the most common dream on record — about 82% of people have had it. Falling (~74%), school (~72%), arriving late (~59%), flying (~50%), and teeth falling out (~39%) complete the core set. The remarkable finding across fifty years of this research: the same small set of dreams recurs across countries, cultures, and generations.
The numbers below come primarily from the Typical Dreams Questionnaire research line — most prominently Tore Nielsen and Antonio Zadra's studies of university samples, which asked thousands of people which of 55 dream themes they had ever experienced — plus a dedicated 2018 study on teeth dreams. Percentages are lifetime prevalence: the share of people who report having had the dream at least once.
How common is each dream?
What the numbers mean
Three things stand out. First, universality: the top themes are stable across cultures and decades — Chinese, Canadian, and German samples produce nearly the same list, which is part of why dream traditions separated by continents and centuries kept writing entries for the same dreams. Second, negativity bias: the most common dreams skew anxious (chased, falling, late, failing), consistent with the threat-rehearsal theory of dreaming. Third, the gap between having and recurring: many people have had the teeth dream once; a much smaller group (~8%) lives with it on repeat — and recurring dreams are where the tradition readings earn their keep.
Nocturnary's own pool statistics — which pairs of symbols are dreamed together, how themes move week to week — will be published as the quarterly Dream Census once the pool is large enough to report honestly. Until then, this page carries only the published science.
Questions people ask
What is the most common dream in the world?
Being chased. Across the standard Typical Dreams Questionnaire studies, about 82% of people report having had a chase dream — the highest prevalence of any measured theme. Falling (~74%) and school dreams (~72%) follow close behind.
How common are teeth-falling-out dreams?
About 39% of people report having dreamed of their teeth falling out at least once, and roughly 8% have it as a recurring dream (Rozen & Soffer-Dudek, 2018, Frontiers in Psychology). The same study linked the dream to real dental tension — teeth grinding and jaw irritation during sleep.
Do men and women dream about different things?
Mostly the same themes at similar rates — the Typical Dreams research found the top themes remarkably stable across gender and across decades. A few differ at the margins (women report more school and exam themes, men more physical-aggression themes), but the shared human core is the striking finding.
How many dreams do we forget?
Most of them. Dream recall depends on waking during or shortly after a dream; within minutes of waking, the majority of dream content fades unless it's written down — which is why capture-it-now journaling works and 'I never dream' almost always means 'I never remember.'
