If you work in NLP, psychology, or sleep research, you've probably noticed something: there's no clean, structured, open-source dataset of dream symbols with clinical interpretations.
The existing options are either tiny (50-200 entries annotated by a single researcher), locked behind paywalls, or folk dream dictionaries with no scientific grounding.
So I built one. 985 entries. Open-source. Psychology-grounded. Free.
The Data
Each entry looks like this:
{
"slug": "teeth-crumbling-dream",
"keyword": "Teeth Crumbling in Mouth",
"icon": "🦷",
"category": "body",
"summary": "Gradual erosion of control or confidence. Unlike sudden tooth loss dreams, crumbling indicates slow, grinding stress rather than sudden shock.",
"date": "2026-05-28",
"url": "https://tool.heartyearning.com/dictionary/teeth-crumbling-dream/"
}
Six categories: life (259), body (202), spirit (148), animals (135), nature (114), people (105).
Where the Interpretations Come From
Not folk wisdom. Every entry is cross-referenced against:
- NIH NINDS sleep research
- Jung's analytical psychology (archetypes, shadow work)
- Dr. Matthew Walker's work at UC Berkeley (Why We Sleep)
- Nielsen & Levin's neurocognitive model (Sleep Medicine Reviews)

I built this because the dream symbols people actually search for — body horror, existential terror, social anxiety dreams — are exactly the ones major health publishers won't cover for brand safety reasons. If you're researching dream content, this dataset fills a gap nothing else does.
