Can You Have An Afterlife Experience?
Is it possible to have an Afterlife experience without actually dying?
Sure, it has been recreated in a lab already, as well as the spiritual experience. It really depends on specific waves such as magnetic waves hitting a specific area of the brain which produces the feelings, thoughts, and even images and situations that people report in near death experiences. It is part of the reason that I do not believe in real near death experiences because it can be reproduced.
No, a true afterlife experience cannot occur before death. Hence the word "afterlife". If someone believes they have had an afterlife experience without dying, it is either a figment of their imagination or the result of outside influences, as Konquererz suggested.
Only if you count an out of the body experience. Some people see OBEs as being a type of death.
