I think that most spirutal beings that inhabit objects exist in a reality behind this one, like a peice of liminate over some paper, and because our two dimensions have different laws, they collide, like a numbers in a mathmatical sum, and combine to make a set of other laws. In ours, everything strives to live, even dead things do, and I think many antient sivilisations realised this, terracotta armies for example, for the afterlife.
