Does dreaming of myself dying signify an indication I am unable to resolve my own issue(s)?

This morning I dreamed I died and to prove if I was actually dead, while deep in the dream, I moved to the corner of my bed and purposely fell off landing of my left shoulder. I concluded if I felt pain, I would be physically alive; no pain would indicate death. I felt no pain; just remember l landed on the floor and felt nothing. I laid flat and somehow maneuvered to the bedroom door, I guess to leave the room, but could not get up and ended up in the corner. I was not frightened; just did not have a direction of what to do next. I realized in the dream I did not want my son to find me dead as that would be devastating for him to find me, so I woke up. My son and I are close so that part I don't question but why would I need to prove to myself I was actually dead or not? Wouldn't one know? This is the 3rd dream I have died; the first one was quite positive and the 2nd was more like this one: proof. Do I need intervention, you think? I am not afraid of dying, but this was kinda eerie.
