Does the “Complex” Wave Function in Quantum Mechanics Represent Anything “Real” at all?

It is an attempt to interpret the role of the universal constant 'c ' the velocity of light, in fundamental physics. It cannot be just be setting an upper limit to velocities of material particles. It must have much more crucial contribution in foundations. In addition, it is also important to recognize the new phenomenon discovered from Dirac's relativistic quantum theory, namely, 'zitterbewegung'. It shows fundamental particles such as electrons must have an 'internal structure' which we have failed to recognize in spite of overwhelming evidences so far. It leads to a fact that electrons travel along helical trajectories and its representation come out naturally as 'complex' exponent. Thus it gives a new interpretation to the complex wavefunction!
