Have you ever had an experince with a mythloigcal creature(yeti,troll,etc) or been abducted by aliens?

believie it or not i me and two of my friends went to iceland bout two years ago...we went on one of them big truck tours and the same morning as we covered a couple of hills my friend saw with his binoculars someting in the distance running quickly. and i'm talking about a place in the middle of nowhere he had a harder look and so didi the tour guide and the rest of us but we didn't see anything. my friend said he wasn't lying but he saw a huge man like beast it was brown and it moved soo fast he couldnt see it well... the tour guide layghed it off saying the cold made him halucinate..but i do believe my friend...i'm guessing he saw a troll or something...
