I mean the obvious connection is that Heather is the reincarnation of Alessa, a person who created an entire psychic universe out of the paradox out of both her suicidal wish and her inability to die and find rest in her suffering. You know, like a ghost.
Interesting that you mention Heather being a reincarnation because the whole idea behind the Eastern belief for reliving the suicide is that you were
denied 
your chance at reincarnation until the time of your actual death because it was your punishment for committing suicide. So that belief is actually counter/anti-reincarnation .But I won't rule out your theory.
