Dreams about tattoos often symbolize identity, permanence, and self-expression. In your dream, the act of someone you used to know forgetting about your tattoo could suggest feelings of being overlooked or misunderstood in your current life. It might reflect a desire for recognition of your individuality or the aspects of yourself that you feel are not acknowledged by others.

The touching of the tattoo could indicate a need for validation from this person or a broader desire to have your experiences and expressions acknowledged. It can also hint at past connections that still hold significance for you, possibly indicating that you are processing those relationships and how they relate to your sense of self.

Consider how you feel about this person and your tattoo in waking life. Are there unresolved feelings or aspects of your identity that you feel need to be expressed or recognized? This dream may be encouraging you to explore those thoughts and perhaps communicate your feelings more openly to those around you.
