It's interesting you have that recurring theme which seems to be dealing with your own mortality. I have similar dreams in which I see myself shot, or am in the mist of a natural disaster where I have to find some way not just to protect myself, but others as well. The dreams are full of anxiety and are extraordinarly vivid. Usually with these dreams, I am up against seemingly impossible cirucumstances and have to find some way to overcome. There is nothing glorious, cavaleir, or theatrical about these dreams. They are very serious, dealing with ultimate curcumstances, and pusing myself to workthrough. There are very few dreams that I have been able to readily recall throughout my life, however these dreams are very easy to remember. They all have the same or similar themes of facing an impossible situation and dealing with these situations on my own.
With your situation, are you the type of person who tends to overthink or over analyze or take responsibility upon yourself for many things?
