I had the craziest dream...

It went off with me and my mother going to this tiny restaurant place. It looked really shady, but we were hungry. As we ate there i saw multiple arcade games. And a thing called "BLJ" points when you win. The levels were really easy at first. I stopped cause I ran out of coins. Then I remember seeing a tiny girl peek out of a door down a long hallway. The owner then asked if I wanted to apply here and I said no since I am moving somewhere. The owner got mad and as be was getting mad I saw a boy play the arcade, but I saw he was at a higher level. He lost, the screen said "you are mine" and he began to disappear. I was scared then Later on I was some reason older, I met some odd people who were my friends. And I asked about the place and they told me to never play the games. Cause if you lose, you become a mind controlled sex slave. Then I remember that girl who looked like this purple haired blue eyed anime char (Mizore Shirayuki) who was the girl peeking out of the door.I said we needed to save them a girl, who was my friend, told me it was impossible. Then a guy came by and said it is possible. We just needed to hack an arcade game and beat the whole game. Then they could be saved. So that's what we did. Or...tried to do. That girl who spoke out played first and lost near the end. We tried to stop the process be she disappeared. We were devastated. Though we ran outside and saw that the FBI, or a team, was helping the bad guys. And one was carrying our friend to the place. One saw me and they began firing. (This dream felt long really long btw. And I hated it. It is still in my mind). We fought back and eventually got their weapons. We busted inside and say our friend who had nor arms pleasing some guy. We killed the guy and took her. The things she kept asking us, I won't say. Then we ran into the owner who looked very demonic. And many little children,boys and girls, crawled behind him, naked. It was horrible. All of a sudden everywhere around me began to light up. The numbers "777" came across many walls and the demonic being was yelling at me and we fought. I won, remembering that I had a reason coming to that place to save those people. I was really injured but all of the children gained conciousness and looked around. Feeling very ill. I was able to heal the friend's arms. And restore those kids. Bringing them back to thier families. All except that purple haired child. Who was an angel as well...and my sister. Which I woke up shortly after. Melody. That name was echoing in my head.
