There cant be flow in pure real and pure imaginary wave functions.
In stationary states the flow is either zero or constant. div D = ρ implies that stationary states create static electric fields. rot H = J + D/t implies that stationary states with J≠0 create static magnetic fields. Static magnetic fields induce currents J which create induced magnetic fields. Time dependent magnetic fields induce time dependent electric fields (rot E = - B/t), which means time dependent charge densities to which correspond non stationary states.
