Dream of father

Me, My late father and my 10 year son were standing on a railway bridge to see a very large steam engine standing on the other side of the bridge. Suddenly the engine starts and takes a very high speed. We did not have other options left, other than jumping from the bridge. Me and my father landed safely and started searching my son. Suddenly we heard his cry from a bush. When we found him crying he was physically all right. Dream ended.
