The ambulance is a vehicle and as such relates to how you are moving through your life. Since it specifically connects to injury and illness as a rapid transport toward healing, it has this sense of rescue at the heart of it as a symbol. Given that there is a siren associated with an ambulance, in a dream it may also operate as evidence that something has occurred in your inner landscape that reflects danger or breakdown, the details of which may be unknown to you at the time.

A dream of an ambulance is an omen that could be taken as a warning against carelessness and indiscretion leading to some major catastrophe in your life. In all cases it is concerning itself with your health, or the inner fear you may have of having contracted some kind of disease, and warrants a trip to the doctor to set your mind at ease.
