I had a last night. i never had a dream like this. it started when i was at my old school and there were these guys i knew them from my school but never talked to them they looked at me. but i keep walking i seen one of my friends and he seemed really mad. he's sister called me over by her and she told me one of those guys hit him. i got really mad and i went by those guys again. and i went up 2 everyone 1 and asked if they did that to him. there was this one guy in the group with them who started laughing he was the 3 guy i think. and i got mad and started yelling at him but he pulled a side and told me it wasn't him all my angry when away. we walked back in the school together and where talking and he asked me out ( if felt like i've always knew him. like we been friends or whatever for years) i said yeah but i didn't mean too. he did something and i got mad and broke up with him i don't know what that was about though and i left the gym he went after me and told me how much he cared and stuff. and we kissed and hugged. went went up stairs an it untiled into a house we went to this bedroom and a guy was in there i knew this guy but he was playing video games. i went into the other room where there was a girl i knew her too. we were talking and laughing. i came out of the room and the guy said if i go out there i will see 3 things happen. and the guy i was with (the one i guess i'm dating) wanted to leave. but i wasn't sure but he left and i went with him. a few minutes later something happen. like an earthquake. ad the stairs broke it was moving around with us on it. he had me jump onto another floor a lower floor. he made it too. we went running. we seen people getting taking over by something i'm not even sure what it was. they tired to attack us. we ran i didn't understand this at all. we run into a bedroom and locked ad blocked the door. we went to the side of the bed. and he held me. i can see that he was scared and so was  i. about an hour later. it stopped we got up and he looked out side the door. that's when i noticed he was bleeding when the side. i started to freaked out. but then it was gone. i freaked out even more i didn't understand what was going on. the next attacked happen. he was hurt again. i started to cry when i tried to stop the bleeding but he told it was okay not to worry about it. i didn't talk after that. i was laying on the bed. and he just came by me and laid with me. then one of those things broke into the room. and the guy i was with turned into something and told me to run. i ran into the bathroom. it was the only room with no windows . i locked the room and i just sat there. after that attack i ran out of the bathroom to the room we were in. he was  gone. i didn't now what happen. i yelled his name a few times. and the next and last attacked happened. whatever they were seen me. i ran back in the bathroom. and my phone started to ring. it was my mom. i told her to stay away until i called her she said she knew what was going on and it was someones fault but i can't remember the name. then i just told her to stay away she said okay. after that something tried to break down the door. i ran to the door and put my body to try to hold me back. but they still tired. and that's when i woke up... i could feel when whatever it was, was trying to break down the door on my back and i freaked out.. i looked at my phone and i had one miss call. and now i can't stop thinking about that guy i'm not even sure if he goes to my school.
