Hi Maria!Very good question! INfact,although we all have the feeling that the afterlife exists,no one really knows what lays beyond "death".Whether we have experiences or not (OBEs for example),most of the time people will always have different experiences and see different things,given that we always interpret what we see "there".Robert Monroe saw things that other didnt even spot.To me,it obviously exists.I KNOW that it exists,because of the few experiences i have had up to now.But what rings true to me doesnt always ring true to other people,there is no ultimate truth
