Popular accounts of quantum mechanics and cosmology increasingly invoke metaphors of “layered realities,” parallel universes, or co-located worlds accessible through perceptual or conscious “tuning.” While such metaphors are rhetorically compelling, they misrepresent both the operational content of quantum theory and the physical meaning of decoherence. In this correspondence, we argue that scalar-time physics (Time-Scalar Field Theory, TSFT) admits no ontological multiplicity of macroscopic histories. Instead, persistence of information requires dynamically stabilized resonance structures within a single continuous scalar-time manifold. Unrealized possibilities do not constitute parallel realities; they dissipate as non-propagating phase fluctuations once coherence is lost. We show that neither observer consciousness nor neural resonance functions as a selector among coexisting worlds, but rather as a coherenceparticipating subsystem embedded in the same scalar-time geometry. This framework preserves quantum indeterminacy without invoking ontological inflation and maintains empirical accountability through experimentally testable coherence dynamics.
