Ok, when i was 15 (42 now) my school hiking club went to the lake district for a weeks youth hosteling. The girls and boys split up and us girls were allowed to be one day ahead ( and in another hostel ) of the two teachers that were accompanying us on our week away.
Anyway, we were supposed to be staying at Black Sail that night and we made it late afternoon. For anyone that doesn't know about Black Sail Youth Hostel - its very remote, in a valley if my memory serves me correctly and a good 8 mile walk from where the school mini bus dropped us off.
It was Winter so we unpacked our bits and there was a party of rock climbers there too - probably about 12 people in total maybe a couple more, it was just getting dark and a bit foggy, everybody was outside having a drink and a chat when out of nowhere a guy arrived sounding really panicked saying (in a really strong scottish accent) that his friend was injured in a gulley and he could not get him out, please, please could we help?
Of course the guys who were there galvanised into action getting all their ropes and bits and bobs, it was pretty much dark by then and we girls were feeling pretty hopeless as there were no phones or anything there ( or there wasn't back then I'm pretty sure) when suddenly someone said ' where's he gone'?
It could only have been a minute from the time he arrived asking for help to when all the boys had gathered their bits and no one noticed that he wasn't talking to them and had literally vanished! I think everybody was so busy getting their stuff that no-one looked at him or spoke to him and this place is so remote that we just couldn't figure out where he had gone or why?
So dissecting it around a fire a couple of hours later, jokes were made about Jeremy Beadle arriving in a helicopter or someone was really pulling all our legs. The thing that was really weird was that it was pretty much dark when he came out of the fog, he had no headlight on his head ( or helmet that we could see) and really and truly no one really saw his face or what he looked like just remembered the panic in his voice.
That night i had the bunk closest to the window, i remember not being able to sleep and dying for a wee but the loo was outside and there was no way in hell i was going out there! Jokes were being made about the 'ghost' before we went to sleep and i don't think i have ever been so bloody scared.
You have to stay at this youth hostel to realise how remote it is for someone to come and make up a joke like that - an 8 mile walk from the nearest road is quite a way.
When we finally caught up with our teachers a couple of days later at the end of the holiday - the story was still circulating and i thought they wouldn't believe us but we were a group of 5 girls and the rock climbers were still there i think so this was a thing that happened to a group of people - not sure why in hindsight we didn't think it was weird that he had nothing on him, no light, anything. Just sort of appeared out of the bloody mist!
