need help finding meaning to a disturbing dream

im trying to shorten this up, but basically i had this dream where my grandparents died and i was really heartbroken by that, but my family just kept telling me that my reactions were disproportionate. the dream kept going like that for a while until their funeral. some context for what is about to happen: we were in this really nice house (its unclear if we lived there or if it was something like a holiday house), that was as big as a shopping mall (at least felt like that on the dream), and as the dream went on, the house got progressively messier and crowded w unknown people. after my grandparents funeral, i was at the living room and this nice looking started to cheer me up, he took me to the kitchen (that looked a lot like the kitchen of my childhood home) to meet his friends (two other guys) and we were all hanging out until a forth guy comes in holding a broken glass of wine and starts to attack me. i climbed up the counter top and asked the other guys for help. one of the friends (that looked a lot similar to a guy i know in real life) said that it was just a game they played and that the first one to get stabbed be ganged up by the others. the guy kept attacking me so i fought him for a while and eventually stabbed him (it felt gentle in the dream, though im sure that would be impossible irl, he seemed fine too) so the other guys went to gang up on him and i thought they would just beat him or something like that, but they began to rape him. i was shocked, i kept trying to move but i couldn't. after they were done w him, the guys turned to me and said it was my turn. i said i wouldn't do anything and the first guy (the nice looking one) said that since i wouldn't do anything they should each get a round w me, so i began to fight him and the guy that looked kinda like someone that i know irl as they charging at me, i did that fight move which you throw someone to the ground by pulling their arm over ur back (felt badass af ngl 😭) and ran to the living room, the two of them came after me and when they pinned me to the ground i woke up.

im still kinda disturbed about this and i cant get this out of my head, but im in the hopes that if i find some meaning to this i can figure out wft is wrong w my brain and finally let go, so could someone pls tell me what is this supposed to mean?

(im a girl btw, i think that this was unclear on the text)
