What do these dreams mean?

I've had several dreams on being stabbed, occurring mainly in the face and heart, by like serial killers, but I've never seen them in my life. I've also had a dream where I was hiding with my stepbrother under a trailer (which is beside the house) while there were hundreds of killers, but they were the same person. There was also a dream where I was in a street at night (empty street) with my mom, and two older brothers, and I was walking behind them, as they were leaving me behind, and I randomly stopped under a streetlight and started calling "wait, wait!" and they wouldn't wait, and the streetlight sent flames onto me, and while I was on fire, my mom was holding my brothers hands, and watched me burn while walking backwards. Also there was this dream, my girlfriend is confused about is she had a dream about her and this chick she really hates and (she had to recently pretend she likes her in real life, oh and the chick is my ex, my first love) they were hanging out, at her dad's house in a different city, and I was apparently hanging out with the guy I dislike (because he used to flirt, and made her like him) but in the dream they were best friends and me & this guy were best friends, and we got arrested for something (she doesn't remember what exactly for) and got dropped off in front of where they were at her dad's house. And we all started laughing together, but yet everyone was worried for everyone. OH and also, she had this dream of an indoor amusement park (I don't know if you guys are familiar about this place, but Galaxyland in West Edmonton Mall, in Edmonton, Canada) but it wasn't normal, it was covered in green goo, and whenever she woke up or thinks about it in general, she starts having a huge headache. Can I get a dream interpretation for all separately, please? We both want to know what these dreams mean.
