The answer in regard to the soul feeling pain or pleasure after death is quite simple.


When we have dreams, we feel pain or pleasure within them, although we don't be doing the exact acts in reality. We may taste something or feel something within a dream, however - we never really tasted it in the physical aspect of the body. Rather it is a concept which is quite unexplainable, and even if it is explainable - then it shows that this kind of thing can occur and is a reality.


The same can be applied to issues of the soul. I.e. what people go through in the grave will occur to their souls, however - what occurs after that - i.e. in the hereafter of the Day of Recompense, the Paradise and the Fire will be physical.
