Nightmares {Erwin Smith x Reader}

-This is an Attack on Titan/Shingeki no Kyojin fanfiction. - I, in no way, own Attack on Titan or the character Erwin Smith. The cover is also not mine, so the credit goes to the artist! - This fic is awful and I'm sorry. I wrote it in one night and I welcome any and all criticism. Thank you for reading!
