Kudos to Mary for saying what many of us probably wanted to say.
I believe in life after death. Our soul is our mortal human container inside which resides is our spirit, celestial energy, which is who we are, our consciousness. Your spirit is connected to this container via a silver cord or particulate energy.
NDEs and Astral Projection is where you temporarily leave your fleshly container and go travel or whatever that is why you can see yourself in the hospital bed, but you are still connected to your body via the cord.
I don't care whether anyone here believes it or not, this is what I believe, and no, it's not something that can be dissected under a microscope.
I remember someone telling me, that when you are close to death, your life flashes before your eyes, supposedly these are your memories being uploaded to your new "body", rather like packing and unpacking a suitcase.
1 Corinthians 15:36 " Foolish one! What you sow does not come to life unless it dies."
It is the mortal container that dies and just as the fallen angels shed their mortal containers to flee back into the spirit realm, people will be transformed to a spirit body in a similar way. Your fleshly container will die without your spirit giving it life-support, but you will be transformed into an incorruptible spirit body. That means that your new body will be beyond harm in the spirit realm for flesh cannot survive on the other side, it must die off during the transformation process.
