What does this super weird dream mean!?!?

In the dream i was five and my sister was 2 and mom was 29 and we were in a car coming out of a tunnel that went through a hill onto bridge which was above a grassy plain and very high up like as tall as the empire state building an all of a sudden my mom driven off the bridge and we were litterally plummeting to the ground which immetiatly turned to water instead of being grass and as we were going down i had the butterflies and then we crashed into the water and died. the dream was foggy for some reason I cant explain. when i woke up i had the butterflies in my stomache like in my dream and couldnt go back to sleep.What does this mean? I dont need a therapist or anything im perfectly fine but whoa the dream was crazy!
