[Byleth's voice was slow, his brow furrowed as he considered the theory Howl put forth. If this was a copy, then what was it copied from? If from their memories, why was it so distorted? At least, some of these worlds were vastly different from the original...]

I'm not sure. If it's a copy, then the Oracle would've taken the template from our memories... but it's not a faithful imitation... then, could it be these worlds are influenced by our subconscious views of our worlds? What we wanted for them, or how we percieve them...?

[Or something???]
