what does this dream meant ?

first its a weird dream like a movie like when i wake up it stops and then when i fall back asleep it starts right where i left off its weird.

but ive been having the dream for the past 2 days and the first day it was weird but not that bad it was last night that it was weird. there was this guy and he wanted to not kill but like capture my brother sister and me. and my mom just took off and later in the dream she said it was because it "had to be like that" like it was a ritual or something and if we didnt obey we would die or something and my brother and sister were captured by him and then i remember i was hiding in the basement (and it wasnt my house it was some random shack that i have never seen before) and i had a gun and then the next day (in the dream) in the morning i was telling my mom, this was before she left, that i could leave now while its still morning cuz he only comes at night

she said NO cuz he will find me and wont stop until he does so it would be easier to get it over with now. so THEN my mom left and it as night again and i was in the basement but the gun wasnt there and i was really scared and then he got me and then i don remember much but he had me my brother and sister and he like tortured us. i dont remember what he did but i do remember he cut us open and made us take our own appendix out. btw im only 14 just saying, and i was pretty freaked out !!

then after he tortured us he let us go cuz thats what he does he takes you, tortured you then lets you go and we were all living in a nice apartment with my mom brother and sister and it was ok but in the dream i have this constant fear that he could come back and im scared all the time (in the dream) and the worst part is i know he is coming back cuz its my dream and i know whats gonna happen but the me in the dream doesnt know so it weird. and i woke up this morning and the dreams topped where we re just in the apartment and when i go back to sleep tonight its just gonna pick up where i stopped cuz it does that.

so what does this dream mean ?? it really freaks me out. and i have never been through anything traumatic like losing a loved one or rape or seen murder or anything like that. i mean i love scary movies so i have seen A LOOT of like gory and scary movies.

also im thinking it might have something to do with this:

so 10 days ago we went to go live with my dad cuz my mom went to washington state to get a job and find a place to live and then we are gonna fly out there and live with her and its a big move cuz we live in south america. i was born in nj and 3 years ago moved here and now we are moving back to USA. and its weird without her cuz my dad isnt a big part in my life like he didnt take off, they just got divorced when i was 6 and ive been living with my mom ever since and only see my dad sometimes and now im living with him so its weird.

my sister said its a stress dream but im a very chill, go with the flow person. i never really get mad or stressed or nervous im just chill and i dont feel stressed.

so wtf is up with my dream sorry its so long

oh and idk if it makes a difference but my sister is older, 18 and mt brother is 12.
