Conglomeration. [FINISHED]

Open door.

​    I was using my phone, chatting with my friends by whatsapp. Suddenly, I got a message from an unknown number. It said "Hello Johnny". Incredibly, that was my name. I was shocked. I asked him how he knew my name and he said that that didn't matter. He asked if I lived in number 83, Fincas de Maschwitz, because he was in the garden. I was really scared. I lived just there...
The lights started to go on and off, interminently. I was now really afraid. I received another message.  It asked if the door of the house was locked. And it wasn't!
Suddenly, I felt a hand in my mouth... It was him...
