A strong gravity naked singular region can give important clues towardsunderstanding classical as well as spontaneous nature of General Relativity. Wepropose here a model for energy emission from a naked singular region in aself-similar dust spacetime by gluing two self-similar dust solutions at theCauchy horizon. The energy is defined and evaluated as a surface energy of anull hypersurface, the null shell. Also included are scenarios of spontaneouscreation or disappearance of a singularity, end of inflation, black holeformation and bubble nucleation. Our examples investigated here explicitly showthat one can model unlimitedly luminous and energetic objects in the frameworkof General Relativity.
