Okay now... I don't believe a lot in such things but an incident happened to me too.
Nothing directly related to "Ghosts" but something creepy.
I was going on my bike, The road is long and covered with trees on both sides. My bike in the middle stopped, which usually happens. This time it wasn't starting with no spotted reason. Well a guy came to me said "Is there a problem? let me help.". I said yeah my bike isn't starting, dunno whats the problem. He got down in the side of the bike and then told me to start it. I did it and then it started. He told me not to come to this place alone at late time. I said thank you, the bike turned off again. I turned it on again, turned back and boom there was no one on the road. The guy might have hid in the trees but who knows. I couldn't see him anywhere and i got freaked. With the bike started i hurriedly got away.
Totally freaked and not knowing what happened i told my family and they just don't believe me lol!
The thing i believe is that it was 2-3 mere seconds that i turned my back on him and he disappeared.
