What would you do if you see a GHOST?

I know not everybody believes in Ghost. Some claim that they see one, while others believe that it is just a sort of imagination.
I never see one but I am afraid of it. stupid, isn't it? Yeah, I say this with shame...I am really coward when it comes to the word GHOST. I can't even go inside the house alone at night.
If you believe or not, that's not the question here... What I want to know is if you see one, what would you do? Would you run, ignore it, look closely, close your eyes, pray or talk to it?

Me, if I see one I think in the next 30 seconds....I would be one of them.
