I dont think that cemetaries are good places for dreaming.....
Cos they are filled with sad thoughts and spirit of deceased people recently that are still close to their physical bodies....They can attach themlselves to a living person: one can prevent these things creating shields but is always more dangerous when ego leaves the body in dreaming.....
Burning bodies is the best way: there's no need to put a dead body into a grave and leave it to rotten for 30 - 40 years ( or more ) even if is about a pet : creates low energies all around by itself without counting the large number of sad thoughts reversed on a specific point ( where the animal has been buried ).
Rudi, ur version I found very romantic: it simbolizes the return to the Father

Archetypes always find a way to express in each one of us...
