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.

Do you change your pajamas every night?

Have you ever tried wearing your  pajamas the second time around? Of course we do wear our clothes everyday, and wash it.Because during the day, we work and sweat and dirty with dust. But my question this time is...Do you wear your pajamas twice or trice, the one you are wearing only during the night when you are about to sleep , without washing it?
Like, when you wake up in the morning... of course you would take off your pajamas or whatever you are wearing and take a bath and go to the office. When you go home, will you wear the pajamas again or get a new one? Some say they wear it again because they only use that during sleeping and would not be that dirty. How about you, how often do you change your pajamas?
