Two Nighttime Attacks in an Old Village House

Something similar happened. Anyway, a friend needed to sell a house in the middle of nowhere. An old half-abandoned village. His grandma used to live there, but she died. But strangely, sometimes people bought houses there. Not for permanent living, since the infrastructure was all wrecked. Like for summer cottages, vegetable gardens and all that, they took plots. So anyway, my friend asked me to help him get the house in that middle-of-nowhere into normal marketable shape (if you can even call it that).

So after the cosmetic repairs, he assigned me a room to sleep in. So I'm sleeping and in my sleep I apparently stretched my arm out beyond the bed. Like it was hanging off the bed. And suddenly someone yanks my arm, and so painfully and hard that they almost pulled it out of the elbow joint. I freaked the fuck out, wake up screaming, and there's no one next to me. At all. My friend came running a couple minutes later (he was sleeping in another room). Asks what the fuck is going on? I can't really answer him. I told him everything as it happened. He didn't believe me. Said maybe I slept on my arm or it was all a dream. But no fucking way, my arm hurt like hell. Okay, whatever. There was still one more day of work left. So again after work I'm sleeping at night. This time I turned on my side facing the wall. I hid my hands under the pillow entirely. I didn't sleep at first, I was waiting for something like that. But then I did fall asleep. And someone fucking whacks me in the back. And the blow was like someone hit me with some object or kicked me with full force. I turned around, and quickly. And... no one, damn it. Here I should say that my friend wouldn't have managed to scram back to his room if he had set up all this shit. Even if he had sneaked up and stood by my bed beforehand waiting for the moment. The thing is, from the bed to the entrance of the room was three meters or even more, and on top of that the floors were creaky and every step could be heard. And also there was no door in the doorway to the room. There were these wooden hanging things, popular in the mid-eighties, early nineties of the last century. So running through them, my buddy would have at least made them swing, and they made a characteristic sound when they touched each other. But they didn't even sway then. I didn't sleep the rest of the night after that. I didn't tell my buddy anything in the morning, he wouldn't have believed me anyway after last time. Thank goodness we got the hell out of there after lunch. By the way, after that nighttime blow I had a bruise on my back. And the place where I was hit hurt for about three days.
