I hid under the covers. Watching my parents get killed. I tried to scream but no sound was produced

I closed my eyes. Hoping this was all just a nightmare. But it isn't. This was reality. The creature is real. The one that's been haunting me. I hid under the covers. Paralyzed from the neck down from fear. I couldn't help myself but peek at what's happening.I watched in horror as the creature dragged my mutilated parents towards the wall, facing me.

I couldn't make out the feature of the creature. However I Managed to see that the creature was hairless. No eyes or clothing. It walked like a caveman, with it's back slouched.
But the creature was much smarter than any caveman. It was aware of what it was doing. It then started rubbing its hands on the walls, drawing a symbol. The symbol looked like a incomplete circle with two small lines across. To finish it off, it scribbled a message on the walls that I could not read in darkness. The creature then disappeared in thin air.
Just like that.

My eyes have adjusted to the darkness. I looked at the message on the walls..

"We will meet again, Matthew."

~I shut my eyes and all the world drops dead
I lift my eyes and all is born again~
