A time-dependent, spin-1/2, relativistic wave equation is introduced, so that some difficulties associated with the free particle Dirac equation may be resolved in a natural and systematic way. It has been found possible to establish a connection between the fluctuation of the velocity and a mass function which describes the fluctuation of the rest mass, derived from the Dirac theory. The time-dependent equation obtained by substituting the mass function for the constant mass term allows the description of spin fluctuations, for example, as time-dependent transitions between nonstationary states.
