If we could have a record of every dream each person had, we would see that everyone dreams of being injured, murdered, killed, again and again. Because these are common themes, some dreams are going to coincide with an actual accident or plane crash.

An accident to someone else: could be hidden aggression. Idioms : accidentally on purpose; chapter of accidents.
