Home page and Gallery page connected?

Somehow, my root page (http://domain.com), and the gallery page (http://domain.com/gallery), became the same page.
When I edit the page at http://domain.com or http://domain.com/gallery, both are edited.
When I go to the dashboard, there is no gallery page, but if i try to create a page at domain.com/gallery, it will not allow me too.
I realize that this is not a gallery thing, it is just a page that somehow got mapped to the root page.
Any idea how to fix this? I just want to delete the gallery page so that I can create a new one.
