Well the last couple of weeks when Kyle, my roommate, and I go to bed, in separate beds, we've been hearing a lot of strange noises. So yesterday my little friend Nate got on my shoulders and poked his head through the "manhole" but saw nothing. So then again when I was trying to fall asleep I heard this "sound" of moving or something right above me and I was freaking out.
Now to today. I hoisted Kyle up there with a flashlight and a machete; I followed with my camera. We saw nothing but a lot of insulation (which is good). He searched and didn't see anything. So tonight when I go to bed, if and when we hear the sounds it is my turn to go up and check.
In the words of the Ghostbusters theme song, "I ain't afraid of no ghost!"
