Whatever they are called, I do believe in them. I also believe there is life after life. When my sister died of cancer, we spent 24/7 with her. She was moved to a room at the hospital that did not get any sun light. She told me she sure wished she could see the sun shine again. The day she died, at the moment she stopped breathing, the sun came shining through that window. Both my older sister and I saw it. We studied that window to try to figure out how that sun came through and why at that moment. Still have not figured it out. I have also heard from her and others since they have died. It is usually in the form of a dream, but I feel their touch and hear their words. I do not care if it is real or not. It sure makes my life easier to know they are there.
