So years ago I heard of a Dr. Ian Stevenson who traveled the world researching children's claims of remembering past lives. I read two of his books, and it was remarkable. Young children would either tell about their other life or think they were still that person. He would then research their stories and find they really did exist in a past life. As they got older, they would get new memories and they would forget the past life.
The scary thing was one of our adoptive children told us of a past life, in exactly the same manner as Dr. Stevenson described. The child said things they should not have known. In any case, I have become a firm believer in this subject.
This now explains my situation. See, I think Cooper, our dog, is an ex-wife from my previous life. I cannot get near my current wife without him getting jealous. And if I kiss my current wife, Cooper tries to intervene. If I try to give my wife a hug in bed, he will jump on us and put his nose between our faces. So now I am searching the web for a researcher who has studied ex-wives from past lives.
