Jack, I think that this forum may not be the place to encounter people who have had experiences with "the other side". You are in a community of people who have had indoctrination that negates those kind of experiences that you describe.
In the JW cult, "other side" experiences/communications are viewed as "communication from demons" or "demon activity".
If somebody who is either still a JW, or is an exJW who has not deprogrammed, has an unexplained experience, the first thing they will do is pray to Jehovah to protect them from Satan.
JWs believe that when a person dies, they have no agency - they are "sleeping".
