Steve ... there is another book you might be interested in called "Dreaming Beyond Death," which was written by a hospice chaplin who recorded the extraordinary dreams that many people have as they approach death.
It sounds as if our subconscious minds know a lot more than our conscious ones do, and understand the transformation that is taking place. I bought the book 4 years ago (long before ALS reared its ugly head in my life).
I can't find it now in my bookcase, naturally, but one dream I remember the author quoting was: The person dreamed he/she was lying in the hospice and there was a lighted candle in the window. Suddenly, the candle was extinguished, and the person felt crushed. But then, the candle appeared on the other side of the window, lighted again and burning steadily. This dream gave the person a great sense of serenity and comfort, and all their fears left them.
Many people also have dreams that resemble "near-death experiences," in which they see beautiful light or meet departed loved ones.
I'm sure you can find references to the book online and maybe some excerpts if you're interested. I think the author's name is Bulkeley.
