As some background information, I'm going to explain my house a bit. I live in an old Cape Cod style house (my family knows a woman in her mid to late sixties who lived in our house as a child) though the house has been changed quite a bit through the years; the signature windows that make a Cape Cod easily recognizable have been removed, the stairs to the second floor moved to a different spot, and-most importantly for this story-the roof over our back porch has been rebuilt, making it much longer. The house is a one-and-a-half bath, and the full bath is on the second floor, where all of the bedrooms are. Having explained that, I can get into my story.
This happened only a few days ago, and I was quite shaken when it happened. I should probably mention that I have hated the location of the window in our full bath since moving into the house; the window sits above the toilet, and at an angle to where you can see out the window when you step out of the shower if you turn your head slightly to the right. The window overlooks our backyard, so I typically put a towel or something over the window when I go to take a shower (due mainly to the fact that right off our back yard are several other houses that are easily seen from the window) the other night, as I was taking a shower, I had music playing from my phone and was waiting for the next song to start. As I was standing in the shower, I heard a series of knocks. Thinking it was someone in my family, I simply ignored it at first, as the bathroom door was locked.
I heard the knocks a few times during my shower, but just thought someone needed the bathroom and continued to ignore it until I was done.
When I went to get out of the shower, I heard the knocks again, but, as I listened, I realized something that chilled me to the bone; the knocks were coming from the window, not the bathroom door. I stood stock-still as the knocks subsided, terrified to remove the towel from the window. I dressed quickly, removed the towel from the window, and ran to my bedroom without looking towards the window. As I sat in my room, trying to calm my nerves, I thought back to the knocks; there was no way anyone could get to the window. For one thing, we have three dogs that bark at anyone aside from my family, and the dogs were silent. And another thing, my father was in the living room, and would see someone walk onto the porch through the back window. And, finally, the only way to get onto that roof is to crawl out my bedroom window or with a ladder, because it stretches out so far, and is too high off the deck to use the railings to crawl up. There was no rain, we have no trees close enough to that window for something to hit it, and there was a pattern to the sound. So what I want to know is, what the hell was I hearing?
