You can get some intuitive understanding of “the wave” as something in space only when you have one single particle. But as soon as you have two interacting particles what you have is a single wave function which is a (complex) function of six parameters (three coordinates for each particle). Add more particles - and their spins - and pretty soon you cannot “understand” anything at all from the wavefunction on its own.
