Haunted?

My heart pounded in my chest as I cracked open my door to peek out into the dark hallway. Trying to keep my breathing steady I edged out, my attention automatically drawn to the empty bedroom I had to pass by. 
It wasn't fully empty, no the extra bedroom had become a storage room of sorts, but no one lived in that room and so I always felt a little bit awkward walking past it.
Because really, a bedroom should be lived in.
I had closed the door a week earlier because the open space just gave me the jitters. But that wasn't all.
Taking another breath I took a step forward. Tense. Watching the doorway.
I walked past the first half of the frame.
Another step.
Still nothing.
I reach the other side of the doorframe. 
Still nothing.
I relax, breathing out a sigh of relief and took another step.
A bright flash of light shown behind me. A quick FLASH before I was left in darkness once more. Blinking away the after images even as I broke into a run.
Not again 
Not again
Not again

I reached the light switch, flicking it up with as much force as I could muster as I turned to see....
Nothing.
Breathing raggedly I leaned against the wall.
Again.
It had happened again.
The bright flash of light.

Seriously, I was beginning to doubt my sanity.
There was literally nothing in that bedroom nor in the hallway that could case such a blinding flash to happen this early in the morning.
Yet, consistently it happened.
Same time, same place.....and only I was experiencing this odd phenomena.
