This happened when I was much younger. I was about 6-7 years old at the time, being half Irish we would always come over and visit and stay in the country side, where it was nothing more than fields upon fields. Little to no street lights. It started how it normally would; getting shopping, going to visit family and attend mass. We were staying in an old cottage, all wooden interior, old school coal fire, it was your your typical spooky looking house.
I would sleep in the guest room by myself in which itself was spooky enough. Whenever I was in this room I would always get a feeling that I wasn't alone. This one particular day I was feeling a bit under the weather and I was playing with my action figures at the top of the stairs (these were swirly stairs, not straight) and I was playing away and then I heard what I thought was my mum shouting to me from downstairs. So I replied but didn't hear anything back. I turned my attention to the bottom of the stairs to look down and but when I shouted back and asked what she wants I still don't hear anything. So as I have turned back round I saw a a cowboy type figure standing at the far end of the hallway. I was in total shock, I still to this day can't wrap my head around this.
After I saw this man I rushed downstairs to find both my parents asleep on the sofa. Which made it all that scary cause I was 100% sure I heard her call out my name. When I had informed my parents they had said how pale I looked, the rest of the time there I had to sleep on the floor in my parents room. First time ever I've experienced anything like this.
