What research shows
Like snakes, over-represented relative to real exposure — a common argument for inbuilt threat responses.

Dreaming about spiders
Dreaming about spiders is traditionally read as entrapment, patience, or something being woven. It is one of the few dreams anyone has actually counted: 33.8% of people report it, making it the 5th most common of the 13 themes with published prevalence.
The psychological reading
The web matters as much as the spider: a situation you feel caught in, or one you are patiently constructing.
What tradition claimed
In much of Europe a spider was good luck and money coming.

Source: Nielsen & Zadra, 2003 — Typical Dreams Questionnaire, n=1181.
Figures come from the Typical Dreams Questionnaire, the standard instrument in dream research since 1958. Dream dictionaries almost never cite a number for how common a dream actually is — the research exists, it just does not get quoted.
The version matters
Different ways this dream shows up
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.
Before you look anything up
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.
