I found this at a dream website:
To see a wallet in your dream, symbolizes financial resources or self-identification.
To dream that your wallet has been stolen, indicates that someone may be trying to take advantage of you.
To dream that you lost your wallet, suggests that you need to be more cautious and careful about your spending and finances.
You need to be more responsible with your money.
Alternatively, it indicates that you are losing touch with your true identity.
Myself, I like the last meaning.
Perhaps that was why the "map" was provided.
Like directions to help you find yourself,
instead of identifying with your job?
or perhaps the "role" some expect you to play?
