I think Ghost type Pokemon can die and they just fade into oblivion. On the other hand there's also another kind of spirit Pokemon when they pass, like Cubone's mother.

Which makes this more complicated. After she was put to rest we never saw her again. So where do Ghost Pokemon come from if they don't come from the deaths of non-Ghost types?

They're just Pokemon that happen to be ghosts. I guess it's like Fairy type, not all of them are actual fairies but have fairy-like characteristics. Any other Pokemon just dies and might leave a trace of energy that manifests in some places like Mt. Pyre or Lavender Town, but they're completely ethereal unlike Ghost types that can be affected in battle.
