  We address the issues related to the presence of the quantum potential term
in a BEC on the observable Analogue Gravity systems. We show that the quantum
potential term apparently gives rise to massive scalar excitations of length
scales of the order $\mathcal{O}(1/\xi)$ in the lower dimensional space. Since,
in 'analogue models', there is a window for experimental observations generally
in (2 + 1) or even lower dimensional space, one has to take proper account of
the presence of these massive excitations to interpret the results.
