Well, that night was horrible. I expected to have a hard time getting to sleep but ended up only getting an hour or two thanks to the rock-silhouette induced nightmares. O_o I honestly felt like I was being haunted by them. Heck, I woke up in my room and went to wake my mother up out of fear and then woke up in my room again realizing THAT was a dream. Got some sleep thanks to lights on, tv on, cats on bed, finally.
Didn't expect a horror story (specially one featuring something as immobile as a hole carved in a wall) to frighten me that much, but geeeeeeeez.
