Fingerprints in a dream signify the need for self-reflection and honesty. One’s fingerprints can be seen as their identity, with the need to be true to oneself.
Also, dreaming about fingerprints symbolize that you feel like you have been exposed, or someone else has been involved. You may feel vulnerable. You might be seeking reassurance that others don’t know what you’re feeling. Or you may also find yourself preoccupied with the idea that people are watching and judging your every move.
In the case of a crime victim, the fingerprints could represent the feeling of being violated by an attacker who left his marks on you and your life.
