This is scary but I don't particularly think this is real. I watched this in one of the prank ghost video compilation. If this is real, I don't know what to say.
Honestly, do not believe in this ghost stuff. The problem with this is bạn can clearly see the fact that this 'ghost' is a shadow. It could of only been that tour guide the man stated he was with.
So as believable as it may be, the answer is a solid no.
