We show that spontaneous breaking of global [Formula Presented] symmetry responsible for small neutrino masses via the seesaw mechanism provides a unified picture of hybrid inflation and dark matter if the scale of [Formula Presented] breaking is close to the GUT scale. The Majoron, which acquires a small mass due to Planck scale breaking of [Formula Presented] is the dark matter candidate. The coupling of the Majoron field to the neutrino induces a small violation of CPT and Lorentz invariance at the present epoch. We discuss some of the phenomenological and cosmological implications of the model.
