My House is Haunted (Maybe) o.o

I used to be a fervent believer in the paranormal, but one two many nights spent waiting at "haunted hot spots" with no results caused me lose most of my enthusiasm in the subject.  So when I moved into my new house last month i was quick to write off the weird sounds I began hearing as the neighbors in the townhouse next door moving around.  The typical situation would have me in the living room with sounds like people moving around, creaking floorboards and the like, coming from down the hall.  This was the direction of the shared wall between the town houses so that explanation sufficed.  A few more days and I began noticing things like doors being open when i thought i had closed them, or lights being on when I was sure I had turned them off.  A tired brain playing tricks on me I assumed.  Then a few days later i managed to grab this video, let me know what you think.
