This happened about 10 years ago.
I was homeless. I had to quickly move out of my last home and the flat I wanted to move into would not be available for a few months. My future landlord and boss presented me with a stop gap. He was renovating a hotel and I could stay in one of the completed rooms until the flat was vacated, rent free! The only drawback was the fact that there was no hot water. I was a young woman of small build and I would be the only inhabitant of an old, spooky hotel. So far, so Scooby-Doo.
I got settled pretty quickly. I hooked up my record player to the TV and bought a mini fridge for my tea making milk, all the essentials. I quite enjoyed the experience as a whole but for one awful event...
I woke in the middle of the night to the sound of someone breaking into the hotel. I was paralysed with fear. My mind was racing. Had I locked the bedroom door? I was so sure I had but I could not move to check. I tried to reach for the phone to call for help but I could not move my hand. I could hear the foot falls of someone racing up the staircase. I was petrified but I still could not move a micrometer. I heard the door knob rattle as my door flew open. A shadow figure ran across the room and dived toward me... then dissipated into the air.
I could move again. It was just a hallucination brought forth by sleep paralysis. Still scary though...
