The wave of one particle is just a suitable approximation. The wave is a wave in configuration space, one for the whole universe. This is also what it is in standard quantum mechanics or in many worlds. It is always the same wave. Somehow Bohmian mechanics gets a bad wrap because it takes the wave seriously despite the other interpretations only having a wave function in their views.
