The meaning of name tag in dream | Dream Interpretation
To dream of a name tag symbolizes your own self-confidence.
To dream that you lose your name tag, or if it’s blank, this suggests confusion about your own self-identity.
If you dream of having the wrong name on your name tag, you may secretly feel that you’re not good enough, and worry that others don’t really like you. Try to improve your confidence level! Also see “Name”, above
