What is the definitive guide to understanding shared death experiences by Brian D Smith?

The go-to resource in my world for understanding shared death experiences (SDEs) is William Peters’ book At Heaven’s Door: What Shared Journeys to the Afterlife Teach about Dying Well and Living Better.

I often describe it as potentially doing for SDEs what Raymond Moody’s Life After Life did for NDEs. William is the primary researcher in this field and an experiencer himself, and I have interviewed him on my Grief 2 Growth podcast and YouTube channel.

Would you like a short summary of the key insights from At Heaven’s Door and how SDEs can help with grief?
