Probably One Of My Darkest Dreams

My mom's bedroom was haunted and there was a mirror in the closet that worked as a portal to another world. If you pressed on it, it got really squishy and you went through. I went through once and it took me to a darker version of my old friend's living room and I saw two of my coworkers having a secret relationship. I tried to get other people to see it, but no one else could make the mirror work except my puppy, but I was scared if she went through she would turn evil or something, so I didn't let her go all the way in.
After taking me home from school one day, I told my mom I thought her room was haunted, and she said something like "it does kind of give off that vibe, doesn't it?" I told her, "Its that mirror," and opened the closet, but the mirror was gone. Then a woman came out of a secret flap in the wall beside the patio window that isn't there in real life. We demanded who she was and she said this was her room, and we said it wasn't and tried to tell her about the haunted feeling and the posessed mirror. I think I closed her flap and trapped her back inside the wall when she wouldn't listen. There was a picture hanging in the closet with a black cat in one corner and some other pictures and words, maybe a crow or raven as well, but I had previously seen it as a blank piece of paper and told my mom. She said that it always looked like that and she was scared I would kill her. She snapped the frame, and I tore up the pieces, and I guess she went to dispose of it. Then Jimmy was in the room with me, but the mirror still hadn't come back, and my mom was not there, and there was an old man in the room. We assumed all this was his fault and killed him. We stabbed him repeatedly with a pickaxe and put him in a box and disposed of the body. The mirror returned, and I think we destroyed it, as well as a squishy stool.
Jimmy and I were driving down the freeway later, talking about our successful murder and everything (I think we killed the woman too) and making jokes, when we suddenly heard a loud bang in the back of our car as we were starting to take our usual work exit. Jimmy said "The lights just went out." We were really scared. I said "Baby, I think we're gonna die." He asked "When?" I replied "I don't know." He then said "Now?" And a car rolled out in front of us.
I forced myself awake then.
