wavefunctions as real, despite their phase freedom,
Heh. It gets worse. Typically one is taught that the wavefunction is defined up to a global constant. You might have thought that the difference in phase between two places would at least be well defined. This is true, so long as you stick to one reference frame. A Galilean boost will preserve the magnitude everywhere, but add a different phase everywhere.
