Perhaps, all writers walk such a line. In general - as we all do in our dreams - I believe I put something of myself into all the characters in my novels, male as well as female.
Perhaps, more importantly, I think that most human beings realise only a fraction of the true potential of their minds, so the spiritual or mystical, the things which remain mysterious or unexplained have always drawn me to include them in any scheme for a novel.
In the planning stage of a book, don't plan the ending. It has to be earned by all that will go before it.
