My friends lost his Dad few years ago. On the night his father died, he was home when someone knocked around 10pm. He opened the door and his dad was there, he asked why he had to travel from the village to that place by that time. The dad said he would explain later but first he needed to rest. Inside, the man called him and advised him, then he went to sleep. The next morning he received a call telling him that his father had died the previous night. When he went to his room nothing was found.
