Our experience has three components — objective, subjective, and intersubjective. They are combined by prana. Without prana they are just possibilities, but with prana they become an experience. The intersubjective has two parts — the observer and the observed. In the dead body, the objective, and the observed part of the intersubjective is present. The subjective (the senses, desires in the senses, etc.) and the prana which combines all three components are missing. So, the dead body cannot have the experience, but it can be experienced. Since the objective component is present, even the dead body can participate in physical interactions if someone wants to interact with that body. But a world devoid of all prana will have no interactions whatsoever.
