New apartment

Update 2: Ok so I talked to my downstairs neighbor, a 65 year old cat lady who makes it her business to know everyone else's, and turns the tenants in the apartment next to mine have been gone on vacation for a while now. I asked her if they had an animal, like a cat or something and she said the girl was allergic to animals, so they couldn't have any...At this point, I was hoping the scratching noises were rats...but maybe it's not. Here's what happened last night:

I went to bed at around 11 pm and put an alarm clock for 2am. I did that so I could wake up and see if something would happen. Sure enough, 2am came and a strange smell filled my room. It smelled kinda like old dried up flowers, if that makes any sens. At first, I could barely smell it but as the minutes went by, it got stronger and stronger. I got up and went to the corridor...only to see my kitchen light opened. Now I'm 100% sure it was closed when I went to be. My heart was pounding as I walked slowly towards the kitchen. My fucking stove was on and the door leading to the balcony was opened...I could see the lock still engaged, how was that possible! I quickly turned off the stove and closed the balcony door. As soon as I did that, I heard a loud bang coming from my living room. I ran to the living room to see what was happening but I didn't see anything out of the ordinary...until I heard what sounded like footsteps on my ceiling! it's impossible, I'm at the top floor, why would anyone be walking on the roof?? wtf is going on! I'm definitely freaking out!
