Since it seems that everything has a self or an identity
Well, there is a distinction between “a self”, in the sense of a mind, and identity. A rock is identical with itself, but it probably doesn't have a mind*. (Not even in a reductionist kind of way.) So, it's probably not the case that everything has a mind.
is it possible that the Universe has its own mind and just lets us discover what should be discover?
I'll define “the Universe” as the entire spacetime system. (If that's not what you mean, let me know.) Are you asking if the universe—the mereological sum or whole of everything that is in or constitutes spacetime—itself has a mind?
*T. L. S. Sprigge and panpsychists would disagree, but they're very much a minority.
