Also posted on the /r/nosleep subreddit but here is my story:
I woke up. I woke up because I heard something moving around the house. Just really quick thumping noises. Almost as if someone was sporadically crawling on the floor. I leaned over to wake my husband only to realize he wasn't there. I couldn't reach the light switch across the room and the thumping just got louder and louder as if it was getting closer. Out of nowhere the bed just started shaking, it felt like an earthquake. I grabbed my blankets and tossed them over my head and started screaming, "THIS ISN'T FUNNY DAN! STOP PLEASE! YOU'RE SCARING THE FUCK OUT OF ME! THIS ISN'T FUNNY!" The shaking stopped. I waited a moment, hoping to hear my husband's voice, or maybe even his laughter from this horrible joke. Nothing. Complete silence. I waited a few more moments, listening close to maybe hear more thumps or anything, anything at all. I slowly pulled the blanket off my head and I see the outline of my husband sitting at the end of the bed staring at me with his head cocked to the side growling. I scream, "GOD DAMMIT DAN! THIS ISN'T FUNNY! FUCKING STOP!" He just keeps staring at me with this huge, teeth bearing smile on his face. I asked him again, this time in a fearful voice because I know at this point something is wrong, this isn't my husband, I say, "Please Dan, what is wrong? I need you to talk to me." His smile disappears, he lunges at me and I bring the blankets over my head once again in a desperate attempt to separate myself from him. Nothing. I pull the blankets back off of my head and my eyes re-adjust to the room and I see pure black. He is nowhere. It's been 3 days. He still hasn't come home. I saw him at the gas station the other day, he saw me too. I ran to him and with a concerned tone asked, "Where have you been!? You just disappeared the other night!?" He looked at me with a confused look on his face as if he had never seen me before and walked off with a quick pace. I don't know what to make of this. It is as if he isn't the same person. I called the police but they haven't been able to find him again. Rome isn't that big. How has he not shown up? I don't know what to do besides wait for him to come back home.
