I thought it wouldn't happen to me
I thought it was only stories
I thought it was something made up to scare people
but I was wrong
it did happen to me
I woke up
but I couldn't move
I heard my bed creak
something appeared from beneath my bed
it wasn't human
it started to knead my back
as if it were a stone that it wanted to break
it moved faster than anything I've ever seen
it hurt
it hurt bad
I screamed for someone to help me
but I couldn't move or even talk
I screamed inside my head
like a comma
I wanted death to free me from that nightmare
a few seconds later all of it stopped  
seconds that felt like an hour
I moved again and the creature was gone
but my memory never let me forget
