What is the meaning in a dream of soot

I dreamt last night that I was at the old house I lived at with my mother and sister but I was with my very close friend laying on the bed and we were eating something but I can't recall what it was,then the dreams skips to me and another close friend of mine fighting each other with knives but we didn't hurt each other with the knives,rather he managed to scratch me with his nails and I remember trying to sooth the scratches with a cloth.In he same dream I attended a weird gathering but in this gathering I was disguising myself because it was hosted by someone that did me wrong and I couldn't afford them seeing me there,I had a whole different name also but everyone else knew who I really was except the hostess,in the end the hostess finds out who Iam and I managed to excape the venue but ran like a monkey rather,with both my legs and hands,later me and the hostess had to sign an agreement,like a divorce,to stay out of each other's lives.I honestly don't know what this confusing dream means

I was in an abandoned building and I was one of two of the last people left in the world. I was there and the person I am in love with but can’t tell was there and we were sad about the world ending. Some explosions happened and the air was completely polluted. The building was the only place where the air didn’t leave my hand covered in sparkling soot. I was about to end my own life with the person rather than be alive in this place.
