The text that boosts me up !

An unknown number kept texting me creepy
Multilated body parts . Thinking the person might be a psycho , I blocked his number .

But the person kept texting from other unknown numbers , no matter how many times I block them . later on, I opened up  the message ,It was the picture of my front door .
After few days , I was home alone one night when I got another message on my phone from an unknown number. It read : "Don't open the door !" I ignored it thinking it was a prank when there were two knocks on the door. 

I went downstairs assuming I was my parents when I received another text," This is your neighbour. A serial killer is on the loose pretending to be the police  to get in .
So don't open the door."

I suddenly froze when I heard ,"This is the police ! Open the door ." Now I was sure something is really wrong .

I switched off the lights, ran towards the kitchen and grabbed a knife. " I know you're in are in there . Just let me in !" The person warned . I was terrified . 
I sat on the corner ready to pounce on him  if he tried to break in . After few minutes the  voice stopped .
I breath a sigh of relief when I received another text . "Now that the police is gone..
Let's meet . I am right behind you ! "
