It's not a topic I would generally write about , or rather this is not the way I generally refers to such things. The reason being is that this type of dramatic terminology, " Dark Nights of Soul ", is very much ego-based. All the connotations are of death destruction , lost-faith , and misery.
In this post, I really focused on why this type of destruction is necessary and what is really being destroyed: the ego. In this way, I would suggest that the dark knight of the soul is an inappropriate viewing of the spiritual rebirth process because in this very idea, the ego thinks something is going horribly wrong and is trying (and failing miserably) to hold on to the things that are being swept away.
