Meaning of "wandering the streets, lost"

[Learning_English]

She was found several hours later, wandering the streets, lost.

Could anyone rephrase or explain this sentence? [Particularly the bold parts]

I know the meaning of every single word in the bold parts but I can't understand as a whole.

Several hours later, when she was found, she was wandering through the streets, and she didn't know how to get home (or didn't know where she was).

Thank you.
I can't still understand it. I am phrasing what I understood : For many hours, she was wandering here and there through the streets because he lost his way, and she don't know where she was".

You understood correctly, except that in one place you wrote "he" instead of "she".
