Fingers can symbolize both mental and physical dexterity. They can also express ignorance and clumsiness.
If you dream that a finger is pointing at you, you may be feeling guilty or you may be ready to change direction.
If you dream that your finger has been hurt or cut off, you may be worried about whether you can perform a difficult task in waking life.
Freud believed that fingers were phallic symbols.
Traditionally, dreaming that you have an extra finger means that you can expect to receive an inheritance.
