Quantum fluctuation
A quantum fluctuation is a phenomenon which can allow for dimensional shifting.

Jadzia Dax hypothesized that the Bajoran wormhole's artificial nature obscured the quantum fluctuation patterns normally associated with wormholes. ()

The Gamma Quadrant planet Meridian underwent periodic quantum fluctuations due to a cascade reaction in the planet's sun, Trialus. This resulted in the planet undergoing transitions to a dimension which intersected our own, where the inhabitants existed in a non-corporeal state. ()
