Car flying off ledge in my dream?

Sometimes I get a dream where it's me my mom and older sister (sometimes my younger one too) in a car. My mom is driving and she's is frustrated because she was going down the road in reverse so to turn around she backs into a driveway kinda on a hill. But she's so mad and us kids are afraid to say anything she drives in the driveway but doesn't stop at the end of it when there's a ledge and we are flying at another yard. At the time I am a little shaken but know we will be alive when we land in the other yard but instead the car seems to turn and we are getting higher and my mom is freaking out because she is so upset that her kids were gonna die like that or something and at first I'm so awed at how high we were I didn't move but stare out the window until my mom says we gotta go now and I'm pushing everyone impatiently through the door before we are too high to jump and before we go over the cliff. I am sometimes in the penger seat or in the back
