if you are dealing with a single world it is a particle
if you are actually dealing with a bundle of worlds it is a wave. It still feels like a single scenario for you.
You can smoothly care about less or more worlds where fewer is more particle-like and more is more wavelike.
The physics offcourse happens in the full multiverse.
Might be obvious or not but now the concept seems like one unified thing for me rather than two disconnected modes having an arbitrary or mysterious feeling connection.
