In the congregation I used to belong to, there was a sister who died after several years of fighting lymphoma. She lived longer than the doctors predicted she would. She had retired and pioneered. She and I went out in service together a lot and I thoroughly enjoyed her. She was a wonderful person. Toward the last of her illness the congregation drew together and provided meals and care for her. After she died, I had a dream, one of the ones that seem to be real, and she was in the dream telling me she was okay. When I woke I felt I had received a message from her on the other side. I was very much in doubt about WT teachings by then and I had no problem with believing she had sent me a message. Of course, I did not express this to anyone in the congregation. Then later on, one of the pioneers in the congregation who was married to an elder told me that a lot of people had had trouble with this sister's death. She did not elaborate on that, but I took it to mean that the sister (Billie Jean) had communicated with others also. I have to say that Billie Jean is the kind of person who would have done that, tried to let others know she was okay, and there is no doubt in my mind that that was what she was doing.
For all you naysayers out there, believe what you want, that's okay. But remember I am entitled to my own beliefs as well.
