I live in Northern Ireland. I was visiting a friend who lives in Bangor (sort of on the East costal area of Northern Ireland), we were walking through the forest after just coming back from the beach. The sun was just setting and as it was autumn it was getting dark quite quickly. We decided to take a walk down to the local shop to pick up some snacks and soda, as you do for a sleepover. As we were walking, I noticed a strange creature scaling the roof of a nearby house…I assumed it was a cat and simply brushed it off. We go to the shop, pick up some goodies and then begin the short walk back to her house. As we’re walking back, talking and all that, out of the corner of my eye I spot something on the roof, this time I draw the attention of my friend – “Do you that over there?” And I pointed “oh yeah…what is it?” We stared at the creature which now appeared to be a lot larger than a cat, it looked more like some kind of humanoid figure crawling up the side of the roof but this creature would have been about 8/9ft tall. We thought that was very weird so we quickly walked back to her place, afraid to look back at the creature but as usual, curiosity got the better of me. I looked back and the creature was no longer there…I looked around and saw it crawling over the rooftops, luckily moving away from us. To this day I can’t find any stories like it, or any accounts of creatures like this…if anyone has experienced anything like this then please let me know.
