I Dreamt Of Lost Sisters Flying Car Bombing Dream

So me and my sister(remmber i dont have a sister or brither) got lost. Our neibors adopted us but the sister was their child and she wasnt my sister. We grabbed a colour pencil, pencil etc for art bcz we are bored. I started heading to my house it was empty...well i slepf i woke up on a dream where me and the neibor's kid was in a flying car. Everytime she introduced me to a building i threw bomb at it on purpose and just for fun. I accidently left one at our houses but it didnt effect it. I asked why to her. She asnwed "oh its just our hourse was made for many years". Everything ended. I was leaving my house with my parents(they are not even my parents in irl or does the sister) i realised i had 3 sister(in my dream). I woke up from my dream i was doing a class on school while the neibor's kid was playing her parents. I decided to ask where is my sister? I did it . the teacher scared at me even the whole class did bcz i dont know...i wake up with a wprried face. I somehow cried from the dream cuz the sisters were murderd.
