people have a tendency to over complicate answers in life. I try to find the simplest answer. As for my experience, it would point to the existance of an afterlife. Talking to those who have passed away is an example. This however does not prove the existance of an afterlife. These entities could be other things like residual energy or trickster entities. Ive also communicated with an aspect of death (ive done alot of research on grim and this is the simplest way to explain it). This aspect was incredible reluctant to give any information on the afterlife, or anything else for that matter. All in all I think there is an afterlife but there is really no way besides dying to be 100% sure and im not wanting to die to test if there is or isnt an afterlife.
to explain the aspect of death thing, this is what my research has uncovered. There are many aspects of death, easiest to explain is like a collective or hive mind. They are all death but at the same time are seperate entities. It is hard to do this kind of research so I cant say for sure this is 100% accurate. this is just what my search yielded.
