...Kinda startled me, but really pissed me off more.
It's 5AM, I just walked downstairs to go to bed, and I open my door and something in the bathroom takes off. I can see it because the light of the nightlight in there is bright on the ceiling, and there it is, solid mass casting a shadow on the ceiling, and POOF it goes away in a second. I see the shadow break up and quickly disappear, because it's right in front of me on the ceiling as I stand in the doorway to the bedroom a few feet away.
Now I'm all awake and shit. Not scared of the thing, just had an adrenaline rush because some fool was standing in my bathroom.
Meh. Sometimes I don't see how people miss these things
