Interpretation 1 — Alison Davies

Passports identify us and seeing one in your dream suggests you’re finding out who you are and learning something new about yourself. To lose your passport is like losing a part of yourself, this could be because of a difficult situation or ongoing struggle. To see your passport stamped suggests you’re looking for approval in some way.
