Nope.. upon further investigation, I noticed some of that dark hair between the storage door and wall, and it seems it might be some kind of isolation material, just like someone mentioned earlier. There's not a lot though. I just need to understand why its been taken out and accumulated in front of my door. I know the storage room is cold and the only source of heat would be from under the door but do rats actually nest? If yes, then I guess the mistery is solved... until then I'm a bit perplexed...
On a side note, a friend came to pick me up earlier (I still can't walk properly), he came in and went out again to wait for me in the car. While I was getting ready in my room, I heard a whistle in the corridor as if my friend was telling to hurry up. I called his name and didn't get an answer... Wtf... I met him in the car and asked him if he whistled at some point and.. he didn't. I was home alone (my brother wasn't hiding in the closet, trying to prank me) but I guess from all the freak happenings I might of just imagined the whistle...
