What is the meaning in a dream of janitor

It starts out when Mom, Dad, myself and several other people I don't know are standing on a beach. Then out of nowhere gunfire or something loud suddenly scares the crowd. I get separated from my parents and I head to the place we are staying but don't see them there. I stay there for a while until I decide to go look for them. The scene changes and I'm in a college for a visit to a campus with my choir. I'm lost and separated from everyone and thunder and lightning are booming. I panic and start crying. Then some people ask me what is going on and I told them I couldn't find my family or choir group. They said they would help me. Then the scene changes for a third and final time. I'm in my church and I see a hallway with a light on just barely showing through a crack in the door. I tell them I need to use the restroom. The restroom was down that hallway. They seemed hesitant to let me go but then they vanish. I reach the door and open it only to see a dead body of a girl. I stumbled back. She looked to have been hung and stabbed several times. I ran into the bathroom and calmed down. The lights went out. I walk out of the bathroom and back down the hall. The janitor was walking down the hallway towards me. I decided to act normal. He grabbed me and asked if I had seen anything. I lied and said no. He started dragging me back to the closet. I panicked and somehow got him to drop me. I ran into the place right behind the center for worship and I see mom and dad. I run over to them and hug them. They seemed just as relieved to see me. The janitor came over and offered to play Rock Paper Scissors with my mom. She said sure. I had a bad feeling in my gut. They played Rock Paper Scissors and she lost, paper to scissors. She laughed and said something like oh darn I lost. The janitor smirked and replied back with yes you did and he stabbed her in the heart with a pair of scissors. He shot dad point blank in the head. I called the police and they came quickly. I ran outside and the cop put me in the car and locked me in. The next thing I know there is a splatter of read and a body against the door and the man smirking at me from the church. The last thing I remember is me screaming that he was going to kill me and for backup to show up. He kills all of them then points the gun at me and a gunshot. That is the last thing I remember before I wake up.

I dreamt that I had to go back to boarding school with my husband. I felt strange being there as a grown woman. I got lost trying to find my way out of the building, going through strange doors until I came out on to the roof. There was the school janitor and other people up there, they were going to tell me how to get out when I saw a sign to the school theatre (where I had spent most of my time as a teenager) and ran off in that direction. Then I saw the roof from a birds eye perspective and saw the janitor and other people turn into a flock of pigeons and swoop down onto school kids below. One girl caught one and flung it down onto the ground. The sky went dark and all the birds were dead on the floor, with blood and feathers everywhere.

Presidential party I am invited preparations are given I am encouraged to attend I back out, spend time in a janitors closet; then I'm in a food court where I meet someone who is to invest in my life I want and then she gives me food and an employment opportunity, courtesy and a new cell phone as well as a chance for a solid relationship, a backdoor entrance past a food vendor into... the dream fades to a black uncertainty before me and then ends
