The eight house is somewhat of a black hole in astrology in my opinion. I am saying this because it covers death, as in something beings undergo without the possibility of undoing. I am also saying this because, like a black hole, this house has remained muchly unexplored in my opinion.
A lot can be discussed about it yet little can be said for certain, even among astrologers I dare to say. There are several reasons for this and one merely needs to look at how this house was seen throughout history as besides death and things connected to it (burials, wills, etc.), it also became associated with the wealth of the spouse (likely based on horary considerations) and over the last century sex and intimacy became associated with it. Moreover, stuff like surgeries and transplants were allocated to this house and it also bears important psychological components, fears being assigned to it.
I am not into psychology and I do not know how this science deals with fears, how they have been analyzed and catalogued. I am sure someone like Scott is way more able to discuss these things from a scientific perspective. What I can say is that I have been actively working with the energies of this house more than once, both on myself and on others, both for pretty things and for less pretty ones.
