The meaning of this dream varies greatly depending on the circumstances and surroundings, but as a rule it is a warning. If you dreamed of an accident as such, you would be wise to avoid unnecessary travel for a few weeks. An accident at sea pertains to love affairs; on land, to business affairs. If possible, you should avoid the thing that was involved in the accident for the 24 hours following the dream, so if you dreamed of a car crash, for example, walk for a day and be careful crossing streets! For at least a day, steer clear of planes, trains, horses, knives, sharp instruments, fires, electricity, high places or whatever pertained to the dream accident; if you can't avoid them, take extra precautions.
