Yep, really. And no, I'm not drunk 

Driving home from work this evening, on the same roads I drive daily. There's a small church I always admire on my way through one of the villages.
Anyway, I pass it this evening, and notice a 'man' in what looked like a bright orange, almost yellow coat / jacket. I remember not seeing anything much, other than that and some legs. I thought it odd since he was stood on my side of the road, on the tiniest slither of verge. There really wasn't much there at all, and it is an extremely unsafe stretch of road in itself. No streetlights or anything like that, just windy country roads.
Anyway, I remember the shock as I saw him, I was thinking why on earth would somebody stand there in such a dangerous spot, let alone barely move out the way so I could pass!
Well. I passed slowly and carefully, before checking in my mirror to make sure he was still okay. When I did, there was absolutely nothing there. Nobody to be seen. The road is surrounded by open fields, no bushes or trees. There's literally nowhere he could have gone to, logically.
I know how stupid this sounds. Honestly if it hadn't just happened to me, I would be reading this post thinking the OP was delusional 🫣🤣
Has anybody had anything similar before?! I'm absolutely baffled!!!!
