Can someone help me

So when I was around 12 or 13 I had a really realistic and vivid dream even though I am a girl in my dream I was a boy who was around the same age I was then I was the oldest child of 4 and I had two brothers an one sister the second one was a bit younger than me I remember having terrible guardians in a run down house the second one he use to do the drugs that the people gave him and theres one specific part I remember he was smoking a cigarette and I begged him to stop and even putting the flame out on the palms of my hand and he used to yell and hit me everytime I tried to get him to stop then it went blank I don't remember but it was bad and next thing I know I'm walking up stairs that go nowhere while carring my sister and holding my brother's hands and when I woke up I couldn't stop crying and even had a panic attack but till this day I don t know what it meant
