What was THAT?

It wasn’t so much the sound as it was the feeling that the sound engendered in my brain.  The feeling was DOOM!

The sound was the slow workings of the tumblers in the lock on my LOCKED door!  Sort of a snick-snap-snick-slide-clunk, then nothing.

Except it wasn’t nothing!  There was pressure, feeling, as if something was pushing against the air coming into my room.

Sweat trickled down my neck, between the hairs that now stood up there.  My heart hammered in my chest, as if to flee that which my brain assured was my immediate death or a fate worse than.

My breath came in gasps, pants, eyes wide to accept whatever the horror that awaited!
