The term POST DEATH EXISTENCE can be summed up as 'AFTERLIFE' (9 letters). AFTERLIFE is a concept that has been around for centuries, and is the belief that a person's spirit or soul continues to exist after death. It is often associated with religious beliefs, such as the idea of an AFTERLIFE in Heaven or Hell. In some cultures, it is believed that the deceased can still interact with the living, either through dreams or other supernatural means.
