He probably saw the energetic imprint of the accident about to happen. I get this sometimes driving through intersections, it's like I can feel the accident brewing - it grows and grows - usually over a couple of weeks - until one day I drive through and there's just been a huge smash. When I get this it means I pay extra attention getting my car through that space safely.
HTH.
Thanks this happens to me and thought i was creating the accidents. Not so worried that i'm the cause now
