wtf was that?

i hear this loud noise just a bit ago, in my room, sounding like its comming from the roof or something above or to the side of my room, and since its in the back corner of the house i have no clue what it was. at first i thought it was something in my mothers room but it wasn't, so i go out side, in rain that just started and was looking around with my nice high powered flash light, and didn't see anything on the roof or on the ground in the front of the house, and nothing in the back on the ground, couldn't see the back of the house cause well there is still snow on the ground, i had my sandels on and its raining so oh well.

makes me wonder...
