  We show that density fluctuations in standard inflationary scenarios may take
the most general non-Gaussian distribution if the wave function of the Universe
is not in the ground state. We adopt the Schr\"odinger picture to find a
remarkable similarity between the most general inflaton wavefunction and the
Edgeworth expansion used in probability theory. Hence we arrive at an explicit
relation between the cumulants of the density fluctuations and the amplitudes
or occupation numbers of the various energy eigenstates. For incoherent
superpositions only even cumulants may be non-zero, but coherent superpositions
may generate non-zero odd cumulants as well. Within this framework measurements
of cumulants in Galaxy surveys directly map the wavefunction of the Universe.
