The neutrino oscillation can arise from not just the genuine neutrino mass term but also neutrino non-standard interactions with the environmental matter or dark matter (DM). It is true that neutrino oscillation indicates some new physics beyond the Standard Model, but it is not necessarily a genuine neutrino mass term. We point out two possibilities of the scalar or dark non-standard interactions (NSI), both of which can induce correction to the neutrino mass term in the effective Hamiltonian that describes neutrino oscillation and hence opens the possibility of faking the neutrino mass term.
