I didn't pay attention to it at first, but as days pass, I decided to tell my girlfriend about it. To my surprise, she too had the same experiences but was hesitant to tell me as well. She said she would sometimes catch a glimpse of someone rushing to the door.
One time, her elder sister came to visit us. The spooky thing was that on her first day of staying with us, she said that she can sense something in the house, not something to be afraid of because it is in fact guarding the house. We were shocked to hear these things from her because we haven't yet told her about the odd things that happened to us.
