So this basically happened when I was in South Korea as an exchange student for a year. It's the only paranormal experience I had whilst I was there but boy will I remember it for life.
I decided to live alone whilst I was there instead of living with other people in a share house or the uni dorm. So I rented a one room near the uni and lived there on my own.
I fell asleep whilst watching an episode of Running Man. (Not relevant but just felt like mentioning that) Suddenly I woke up in the middle of the night, not sure what time, feeling tingles all over my body. It wasn't particularly cold as it was transitioning to autumn but I just felt shivers all over my body and hair raised, goosebumps everywhere. And that's when I heard loud breathing. And it wasn't my own.
For a second I was wondering to myself if I was dreaming and if I was aware I was dreaming if this was a lucid dream. (I've had lucid dreams before and made myself fly or breathe underwater) But after a few seconds of trying to change the dream made me realise I was definitely not dreaming.
The breathing was coming from above me where the ceiling was, I couldn't bring myself to open my eyes. And I pretended to be asleep so I breathed slowly, with a bit of volume. But I don't think I fooled whatever it was. The breathing became louder and closer and I felt it's hot breath, whatever it was. I can never forget this feeling and it made me forget that I was supposed to be pretending that I'm asleep but I inhaled sharply and just froze, too scared to move or make a sound.
It giggled and it was a man's voice. And then I felt its breath shift to the back of my neck and then after a bit shifted again to my right arm. I started praying all my prayers coz I was scared s**tless. Then I felt it's breath on my right hand and then the breath was concentrated onto my pinky finger. Then it bit me! My pinky finger. I jerked my hand way and clambered into the covers because of course that's going to protect me. Stupid. After realising I was being a fool I got out of bed and ran to the light. Hit my hip on the way and bruised it. But after I turned the light on there was nothing there. I don't know what I was expecting. I wasn't about to open the store room opposite my bed or check under the bed.
I looked at my pinky finger and it didn't look particularly different. Just a bit more pink compared to the rest of my fingers. No bite marks. But then again I just jerked my hand away very quickly when it was starting to get painful. I brushed my teeth, grabbed my phone saw it was 3:47am then put on a coat, grabbed my wallet, left the house and went to a 24 hour karaoke. I was hoping singing my favourite songs was going to distract me. I just didn't want to be in that room that night.
I've told other people but they just laugh it off and say I must have been dreaming. But I was not.
