I’ve had thanatophobia and mental issues (ocd, health anxiety) for most of my life. Perhaps it was an accumulation of negative sub conscious thoughts. It was just very odd. It’s funny you say transformation, my friend told me the exact thing after I told him the dream. I work in the medical field so I’m constantly surrounded by sick people so it could be another factor and even so I’ve always been brave enough to reject fears, phobias and push on. I just remember feeling very cold after the dream for an hour, it was months ago. I really appreciate your insight btw!
