Maybe. I do believe in guardian angels, and, I don't think the angel of death is an evil angel. And, the only angel I have ever seen has been the angel of death, so they would be most likely to be my guardian angel.
When I would be in solitary confinement, I would have visions and dreams of the angel of death, comforting me and offering me friendship.
When I have been suicidal, the angel of death told me in dreams that my time is not here yet and it will be one day when the time is right.
I could feel the angel of death, a comforting presence behind me, telling me everything is ok but also warning me, when I tried to take my own life.
I felt them there comforting me when I have had pets pass away
I have been comforted by the angel of death, knowing one day I will cross over.
I see the angel of death in my dreams all the time, and they are always kind to me and sweet.
When my child passed, the angel of death assured me they were safe in his hands, and he gave me closure because I could vaguely feel his presence when I finally let my baby's ashes go into the ocean.
Because the angel of death has protected me from myself, and comforted me during hard times, and I know everyone has a guardian angel, I think the angel of death is possibly mine.
I could be wrong, though.
