  We study the Dirac equation for quasiparticles in gapped graphene with two
oppositely charged impurities by using the technique of linear combination of
atomic orbitals and variational Galerkin--Kantorovich method. We show that for
sufficiently large charges of impurities the wave function of the occupied
electron bound state of the highest energy changes its localization from the
negatively charged impurity to the positively charged one as the distance
between the impurities increases. This migration of the electron wave function
of supercritical electric dipole is a generalization of the familiar phenomenon
of the atomic collapse of single charged impurity to the case where
electron-hole pairs are spontaneously created from vacuum in bound states with
charge impurities thus partially screening them.
