This idea came from another website: This can be anything--surviving an accident that might have easily killed you, seeing something you cannot explain or seeing something that surprises you (for example a friend's grandfather dying unconscious but with a huge grin on his face.) Here is mine: One leaf of a large plant in my living room shaking violently--no vents are near it or fans were going and the rest of the plant was still. I don't know how to explain it (I do not believe in ghosts btw.) Leaving a family bbq ten minutes after my parents, I came to one road and the traffic was backed up and I saw flashing lights in the distance. I somehow knew then and there it was my folks. Thankfully they and the woman they plowed into survived the accident.
