We are all our own graveyards, I believe; we squat amongst the tombs of the people we were. If we're healthy, every day is a celebration, a Day of the Dead, in which we give thanks for the lives that we lived, and if we are neurotic we brood and mourn and wish that the past was still present.
You just have to trust your own madness.
Horror fiction shows us that the control we believe we have is purely illusory, and that every moment we teeter on chaos and oblivion.
Writing about the unholy is one way of writing about what is sacred.
