Most of the time, death is just a symbol for change. Something in your life is probably going to "die" soon, and maybe a trusted individual is trying to warn you. Maybe you're trying to warn/prepare yourself.
I really can't tell you without more information. A lot of it depends on what doctors and death symbolize to you specifically. You dream in signs because the signs make the most sense to you.
Death is a sign of new beginnings. The end of one thing and the start of somethin new.
Dont worry its not a premonition or anything.
