Dear
Welcome to HCM
We understand your concerns
I went through your details. I suggest you not to worry much.
Dream interpretation is an area of psychology which needs a lot of experiments. Psychology studies behavior and cognition. Dream definitely is not an area where full help can be expected from the dreamer. Because, nobody shall be able to remember the full dream.
But every year, lot of psychologists study dream and patterns. In your case, the dream you are experiencing often are exactly your fears. Your fears about death and a particular way of death have caught your mind's imagination vividly and gave face to it. The face is also an imaginative one. Because these are jujst imagination, you never shall experience them in future. Sure.
Just ignore these dreams and there they goes away from you.
If you require more of my help in this aspect, Please post a direct question to me in this website. Make sure that you include every minute details possible. I shall prescribe some
psychotherapy techniques which should help you cure your condition further.
Hope this answers your query. Available for further clarifications.
Good luck.
