I think the process of dying can contain various levels of trauma.  Some people die with less pain, and we tend to call them lucky.  I tend to think the body inflicts various levels of physical and psychological pain over the often somewhat lengthy process of dying.  One type of emotion I can partly relate to is the idea that the party (life) keeps going on, but you have to leave.  The idea of no longer consuming new information or experiences.  The process of dying inflicts bad emotions on me, but thinking about being dead does not inflict many emotions on me.  I feel neutral or calm about the idea, and I see no rational reason for worrying about it.
