What is a soul ?

In order for a soul to interact with what we call reality, it must occupy some mass. The mass has to be at least a few grams. There are rules. The sole may come and go. A soul feels pain and emotions. A soul will not leave just because it hurts. Souls have somewhere else to go when they no longer find this world interesting. Souls do not have mass themselves. Though, some wonder if we may have found them in dark matter.
