Meaning of "nod towards"

[Jokul_Tl]

Here is my question,
Once, my friend asked me, what does "nod towards" mean.
I answered her that means "nod one's head to someone".
But she then told me that means "bend one's head forwards". Is that ture?
And if not, what does that truly mean?

I think "nod towards" is used figuratively to mean that you are inclined to lean towards something, to like it or approve it a little better than others.
