Sometime years ago

I don't remember now what happened. I just
know that I was reading a book. And the house 
got very quiet. So much so that it made me stop 
reading. Then, something happend either a movement
or a sound. I don't know- I can't remember now. I 
think it was both. Know that I'm writing this, 
I remember something more. I froze for a while, 
in the silence, until the unexplained fear subsided.
But then, a small noise from my closet broke the silence.
I got up and one of the little troll dolls that McDonald's 
gave in the kid meals had fallen from the shelve. That's 
it, it had just fallen... Was that it? Is there 
something I'm not remembering still? What caused it 
to fall down anyway?
