To dream of your hands says a lot about your current mood and emotion, but in particular it shows how you are connected with others and how you impact the world.
The right hand represents strength and activity; it shows the human masculine side. The left hand represents the gentle side with generosity and femininity.
In a dream you might see yourself holding hands with someone - this reflects your attachment to that person and the will to keep them close to you at all times. Dreaming of bleeding or injured hands represents a blow to your pride. Alternatively, if you dream of clasped or closed hands, it shows unity and acceptance of the current situation. It may also mean stubbornness and unwillingness to help.
To dream of having oversized hands shows success and ability to reach goals. To dream of having hairy and rough hands shows aggressiveness and lack of tenderness.
To dream of a bloody hand implies guilty feelings over a wrong doing, which may haunt you for quite a while.
To dream of cleaning your hands in flowing water indicates worries that you wish to wash away. This is a desire to cleanse yourself from your responsibility for a given issue.
