Weird 3am email

So at 3am last night I got this email from a stranger:

SUBJ: At 5th street.

Body:

I'd like a map of the city.

Now, this has to be something salacious, right?? What’s creepy is last year I lived of a 5th street, so it made me think. But it also makes me think this is the way movies like The Matrix start…maybe I missed out on something?
