New to the state and was renting a very small room in the upper level of this house. The vibe here overall was really not good but I loved and felt quite safe in my room. This happened not even a month after moving in. I often slept with the window open because there was no A/C, this was one of those nights. I was reading in my bed late one night. This house is off one of the busiest roads in Everett, next to a bus stop and apartment complex, so when I left the window open it was quite loud even late at night. I began to hear noises and immediately thought it was coming from the apartments next door, so I kept reading unbothered. But then it started to sound like human footsteps on the shingles of the roof. I put my book down and really began to pay attention. The curtain was drawn over the window so I couldn't see, only hear. Looking back I think am really glad for this. The footsteps came closer to my window. Like I mentioned earlier the vibe here was bad and the owner told me I should watch out for a person who used to live here and that he might try to get into the house sometimes. Immediately that's where my mind went, and I froze in fear. But within seconds of my realizing it could be that guy, the footsteps sounds quickly morphed into what I can only describe as a rat-sized creature quickly scuttling towards, up, and into my open window, stopping before it entered. This house did have rats, and maybe I was happy that this sound made a little bit more sense than footsteps on the roof because I snapped up in bed to make my way over and shut the window before a rat could come into my room. I did not make it out of my bed before this powerful sense of dread hit me and I froze again, listening to the newfound silence. I thought for sure now that this was not a rat and that whatever it was was going to come into my room at any second, but I was so frozen in fear that I couldn't do anything. Then, after some moments of silence, I heard a noise I've never heard before or since. I couldn't replicate it if I tried. More or less, it sounded like something right outside my window was whistling, but in a way I had never heard before. I was hearing a sound that was brand new to me. It didn't have a discernable melody to it, but there was a very musical and intelligent quality to it, almost birdlike too. But it sounded very taunting, teasing and malicious. There's no way I can be for sure about this, but in that moment I felt in my gut like it wanted to come in but couldn't for some reason, so now it wanted to scare me the shit out of me. After several seconds of this, I heard no more footsteps, but the weird whistling started to fade like it was getting farther and farther away, until it was quiet again. The whole interaction was maybe a minute or two long. I shut my window, and I noticed this weird pattern wiped from the dust on the outside of my window. There are no nearby trees or branches or anything I can think of that would rub up on the window and do this. I've also entertained the possibility of these noises coming from the garage or rooms of the apartment complex right next door but... I just at a complete loss for what could make those noises. I don't know much about the fae but in my gut that's what I felt like I was dealing with that night. The trickster energy, the utterly unfamiliar quality of the noises, and just the terrible bad energy of that home I think would be attractive to some dark entities.
