I saw something today very strange. I saw what looked like a puff of smoke go into the ceiling behind the light at work today.

No smoking allowed.

It was over the desk of the woman who just lost her mother.

I can't seem to replicate what I saw using the normal optical wierdness that comes from wearing high index glasses and shifting vision from screen to distance, or by the floaters that I normally have in my slightly aging eyes. The 'puff of smoke' I saw went up in my peripheral vision, without my shifting my eyes - the floaters only shift in my eyes when I move them.

Did I see a ghost? I don't, btw, believe in ghosts. Generally speaking.
