Identification
To dream of a identification represents a need to prove yourself to someone. Proving your worth, skills, or that you deserve something. Proving you are a perfectly qualified person.
Example: A man dreamed of being told he needed to show ID before getting access to something. In waking life he needed to pass a spiritual exam before being allowed to a higher level of freedom in the church.
Example 2: A woman dreamed of being handed her ID with someone else's name on it and then seeing a sticker with her name being stuck over the name. In waking life she was fired from work for misconduct and had to appeal the decision to try to get her job back. The dream may have reflected her attempt to fake being something she wasn't in order to prove herself as honest when in reality she was guilty.
