I have to respectfully disagree about your opinion that the dead don't talk. My husband deceased father has visited him three times. Two times he materialized in front oh him and spoke directly to him. The other time he spoke in his ear.
My mother also had a deceased friend show up in her car in the seat next to her and she told my mom to stop grieving for her. We have to remember that just because a loved one is no longer in a body, it does not mean they cannot talk to us. They are still the same person that they were when they were living. The only difference is that they are not in a physical shell.
