If you dream of a thumb, you may find yourself drawn into the orbit of clever, manipulative people, and your fortunes could shift unpredictably. A painful or injured thumb points to setbacks in work and friction with the people closest to you. Dreaming of having no thumb at all warns of isolation and hardship. A surprisingly small thumb hints at fleeting pleasures, while an oversized thumb suggests swift and dazzling achievement. A dirty thumb reflects indulgence in questionable desires, and an unusually long thumbnail is a caution against chasing strange or reckless thrills that could lead you somewhere you don't want to go.
