I started having these back since i was about 5 years old. it started with me in the backseat of my parents' car and one of them would be driving on a desolate road, no cars nothing.

but then, in a blink of an eye, they would disappear and i would be in the car alone until i woke up. then my sister was born and when i had the dream again about a year late, she was in it and everyone my parents disappeared again. then my brother was born about 2 years after and the same thing happened. i just had another brother a year ago and i haven't had that dream...yet.

(Not sure if this would be relevant or not, but i also had one where my parents left us in the car to go do something and my sister took the wheel and drove us into an ocean lol)
