I think I'm sending myself letters... from someone else

So, things with me have been getting kinda unsettling over the past few weeks, and, from what I've read nosleep is the go to place for experts on, well, anything fucking weird. It began two Thursdays ago, at night (because anything creepy happens at night, I guess at night the logical part of your brain just leaves you a little, and makes way for all sorts of shit to happen) although i only found it in the morning. And by it I mean the letter. Or maybe note would be more fitting, because you have to send letters, and they're usually longish as far as I'm aware, and this one was just sitting on my desk, no envelope, with one of my pens lying next to it. It is worth noting that when I picked the paper up to read it, I realized I had ink on my hands. I will transcribe the writing below.

My pretty, my pretty, my pretty little girl. I could encircle your little waist entirely with only my two hands. I will. I promise you I will. I will feel your pretty shiny hair, my pretty little one. Your little mouth, with pretty red lips. You’re not pale, you have lovely olive skin. It makes you look so much more alive.

I promise, that is exactly as it was written. At this point i should give you a little backstory. Only a little, but I think it will help. I'm only fourteen, still a child. Just under two weeks off my fifteenth birthday. Sometimes i feel older, sometimes i feel younger, but that is my age. As you can imagine, I did not exactly have experience of this sort of thing. At first I thought that maybe I had caught the eye of some boy at school, ignoring the question of how the letter itself got onto my desk. But the use of little unsettled me, it sounded like someone older. Something more sinister than puppy love, but there was nothing outrightly worrying, and to tell the truth, I was kinda exited at the idea of romantic attention, that somebody found me pretty, so I hid it in the pages of one of my text books, and, me being me, promptly forgot about it. It's the second letter, only last night, that has driven me here, and I'll relate that one to you too. I'm being exact. The words below are the words I found this morning, no editing, no cutting.

I’m coming, pretty, I promise. I hate to think of you all alone at night, sleeping in your pretty little room. You did it yourself, didn’t you. I wish you’d take down those ugly curtains. They block out your pretty window with white every night. Dark white. It shuts out the light.

I'll be honest, this one fucking terrified me. I don't live in a town, nobody would notice if there was someone standing outside my window. But this is not what freaked me out the most. This letter, and as further inspection revealed, the original one, are both written on my paper, with my pen, which is always left without a lid next to the paper, on my desk, no sign of anyone having been in my room, and ink stains on my hands. One final thing. Both letters are in the same handwriting, but it is not mine. I will continue to post any more information that might make this less of a mystery, and I really hope there is somebody out there who can help.
