You found a abandoned building... But there was something different about this... You felt a lot of Deja Vu in there... Like if you been there before, very strange.
You were walking around inside of the abandoned building, because for some reason you wanted to figure out what was giving you those Deja Vu vibes... Then you came across a Hallway. This one felt very similar to you, then you started to walk straight forward in the hallway.
The walls looked very old and some looked new, there were also broken glass and pieces of speakers on the floor. Then at one point you stopped walking and looked over towards your right, there was a mirror, in perfect condition. You stared at yourself for a few moments before you put your hand on the mirror, and then a microphone came out of the mirror and knocked you back.
You looked ahead and see that the microphone was glowing red on the edges before fading and turning back to normal... Your reflection... It was different, it wasn't you anymore, it was someone else now, a very tall and slender like guy in the mirror. He looked very similar... Empty eye sockets as well. Then it started to come out of the mirror quickly. He picked up the microphone with his left hand and looked at you while you were on the ground, he started to chuckle for a bit.
"...tsssk"
"Yourself" stood there, making creepy breathing sounds, he is in a position like if he ready to sing or beatbox...
