We develop a type of Kaluza-Klein formalism in (4+4)-dimensions. In the framework of this formalism we obtain a new kind of Schwarzschild metric solutions that via Kruskal-Szequeres can be interpreted as mirror black and white holes. We found that this new type of mirror black and white holes solutions in (3+1)-dimensions support the idea that the original space-time can be extended to (4+4)-signature. Using octonions, we also discus linearized gravity in (4+4)-dimensions.
