  The approach to incorporate quantum effects in gravity by replacing free
particle geodesics with Bohmian non-geodesic trajectories has an equivalent
description in terms of a conformally related geometry, where the motion is
force free, with the quantum effects inside the conformal factor, i.e., in the
geometry itself. For more general disformal transformations relating
gravitational and physical geometries, we show how to establish this
equivalence by taking the quantum effects inside the disformal degrees of
freedom. We also show how one can solve the usual problems associated with the
conformal version, namely the wrong continuity equation, indefiniteness of the
quantum mass, and wrong description of massless particles in the singularity
resolution argument, by using appropriate disformal transformations.
