Monster do exists

This place is terrific dark . As always I am running on this dark path. Furthermore , I am scared of that particular object of fear that is running behind me , a monster maybe , that would be the right way to call it , isn't it ? I could felt myself out of breath however my fearfulness refused me to stop.

Then I heard those words again in my head ,I couldn't got the gender from the voice itself however , it was a glitchy frightening yet a clear understandable voice.

YOU CAN ESCAPE A MONSTER RUNING BEHIND YOU. HOWEVER

HOW CAN YOU ESCAPE A MONSTER WHO IS INSIDE YOU ?

As those words ended , my legs came at a halt , moreover , the monster earlier stalking me vanished in thin air , with a huge mirror appearing in front of me from nowhere. NOW, HERE EXACTLY IN THE MIRROR I SAW THAT SAME SINISTER FACE WITH A CLEAR EVIL SMILE . I KNEW THAT FACE , CAUSE I HAVE SEEN THAT SAME FACE, EVERY SINGLE DAY IN MY LIFE.

IT WAS ME.

OUR BIGGEST FEAR IS NOT SOMEWHERE FAR AWAY FROM US , IT IS HERE , INSIDE US.
