We propose a conceptual framework in which the pilot wave of de Broglie-Bohm quantum mechanics has a concrete physical substrate: dark matter existing in a fourth spatial dimension. Quantum superposition is reinterpreted as rapid physical oscillation — consistent with the Zitterbewegung predicted by the Dirac equation — rather than simultaneous existence in multiple classical states. Wave function collapse is correspondingly reinterpreted as physical interruption of this oscillation by detector interaction, rather than observation-dependent state reduction. The framework advances a coherence argument against the Many Worlds interpretation: real superposition, as evidenced by the ordered interference pattern in the double slit experiment, produces coherent identical behavior across superposed states rather than divergent branching. Divergent branches would produce detectable decoherence signatures inconsistent with observed interference; their absence constitutes evidence against branching interpretations by the same evidential standard used to establish superposition itself. The Born rule is proposed to be a relational property of the detector-system interaction rather than an intrinsic quantum axiom. Since detector physical constants — mass, charge, interaction energy — are fixed across measurements, probability distributions are determined by the interaction geometry rather than by unexplained features of the wave function alone. The squared amplitude relationship is identified as a universal property of wave energy mechanics appearing at quantum scale. The nonlocality problem of pilot wave theory is resolved by proposing that dark matter exists in a fourth spatial dimension. Particles entangled across cosmological distances in three-dimensional space may be geometrically adjacent in four-dimensional space, making instantaneous correlation a short-range 4D connection rather than superluminal 3D signaling. This is consistent with Kaluza-Klein dark matter proposals and brane cosmology. The inaccessibility of the wave medium to electromagnetic instruments follows naturally from the confinement of standard model forces to the three-dimensional brane. The framework makes several testable predictions: correlation between dark matter density and quantum coherence times; systematic shifts in Born rule probability distributions under varying detector parameters; and potential gravitational wave signatures of large-scale quantum collapse events. Mathematical formalization and experimental testing are identified as open problems.
