Dreams experienced as previewing rather than processing — and the one category where the claim is testable..
What research shows
Precognitive dream claims are common, but the arithmetic explains them: with roughly 4 dreams a night across a lifetime, coincidences between dream and event are statistically expected. No controlled study has demonstrated precognition in dreams.
The psychological reading
Confirmation bias is the mechanism — a dream is remembered as predictive only after the event gives it a shape.

The version matters
Most dream dictionaries give one meaning for the whole symbol. In practice the specific version carries most of the information — losing every tooth and losing one tooth are not the same dream.
How to record a dream, why the feeling matters more than the content, and when recurring nightmares are worth a doctor rather than a dictionary — set out once on the main page.
How the dream felt matters more than what was in it. The same image can arrive as comfort or as threat, and that difference tells you more than any entry in a dictionary — including this one.
