The idea of nature is experience, meaning any experience having nothing to do with positive or negative, just experience for experience sake for expression of sensation, like when one peers into a kaleidoscope. Each time one turns the face of it, and peers one sees something else. It is the same set of particles but arranged in this or that way according to the twist of fate, even the slightest movement/displacement.
Some Buddhists strive to get rid of experience or to remove themselves or what people terms as themselves from the environment which imposes experience. Why? Because experience is the read out of trauma, of unpleasant feelings.
The supposition is that if there is no experience, there will be no feelings which translates into no trauma, no risk of repercussions, no scrambling for control of time and circumstances.
On the astral side anyone who dies instantly in an accident is instantly out of touch with the condition of the physical body and is instantly fully aware of the subtle one. The only pain for that person would be damage in the subtle body. None of the damage to the physical body, no matter how bad it is, would be felt.
And yet, we experience that relatives of such a dead person may react to the situation as if the person was on the physical side and is experiencing the physical condition. That is due to the mental and emotional conclusion imposition which the surviving relatives are subjected to as their experience.
We experience what actually happens and what our minds projects into what actually happens. It is reduced to experience, regardless of whether it is real or imagined.
