Imagery

I'll let you figure out what the true meaning of this poem is.

When you look in the mirror-
What do you see?
What is a mirror-
What is it that you see?

Do you see your reflection-
Or one of someone you don't know?
What's in a reflection-
Can you honestly say that you know?

Do you only see an image-
Like it's someone you don't know?
If it's only an image-
Than how can you truly know?

When you look into that face-
What do you see?
Is it just another face-
Or something you've never seen?
