  We propose a solution to the quantum measurement problem in Inflation. Our
model treats Fourier modes of cosmological perturbations as analogous to
particles in a weakly-interacting Bose gas. We generalize the idea of a
macroscopic wavefunction to cosmological fields, and construct a
self-interaction Hamiltonian that focuses that wavefunction. By appropriately
setting the coupling between modes, we obtain the standard adiabatic,
scale-invariant power spectrum. Because of Central Limit Theorem (CLT), we
recover a Gaussian Random Field, consistent with observations.
