Even though I don't believe in an afterlife, I definitely don't think you're a weirdo. I'd say that what make you or anyone a weirdo in a negative sense is if you can't accept, that different people think differently about various aspects of life.
There's so much to say about the body/soul dualism and one thing is, that there has actually been TWO different kinds of dualism: in the ancient Greek culture the soul was a UNIVERSAL IMPERSONAL IMMORTAL INVISIBLE substance, but in the Christian culture from late antiquity on, we get a quite different soul that carries the specific persons identity. So the so-called afterlife is a very, very Christian way of thinking.
Ancient Greeks could think about "the soul IN Socrates", but they didn’t and couldn’t think about "Socrates' soul". Not because they were stupid, but because they weren't Christian.
