Yes laugh all you want but REALLY, do you? :p
I've heard of so many lately that say that they have seen one and they've been fully aware of what's been going on at that time. To me, it doesn't seem impossible at all that there would be something like that but of course I need proof..I need to see one to believe it!
And I wish I did see one at one time but..it would have to be in the daylight and I could not be alone :p but also...I think I'd never dare to be alone after seeing one :/
Have you SEEN one?
