  In the functional Schrodinger formalism, we obtain the wave function
describing collapsing dust in an anti-de Sitter background, as seen by a
co-moving observer, by mapping the resulting variable mass Schrodinger equation
to that of the quantum isotonic oscillator. Using this wave function, we
perform a causal de Broglie-Bohm analysis, and obtain the corresponding quantum
potential. We construct a bouncing geometry via a disformal transformation,
incorporating quantum effects. We derive the external solution that matches
with this smoothly, and is also quantum corrected. Due to a pressure term
originating from the quantum potential, an initially collapsing solution with a
negative cosmological constant bounces back after reaching a minimum radius,
and thereby avoids the classical singularity predicted by general relativity.
