Yes I do, since of past experiences. I have many weird stories which can not be explained. Both my parents have had weird stories as well. 

I believe in ghosts, 

There has to be something out there. Same as aliens

no but if I saw one I would :p

I have never experienced one, but enough people have seen them to make me think there may be

I believe they exist but not everyone is open enough to the idea of it so they will never experience it. 

I am scared of the supernatural!

yes i have seen ghosts  before  my one school i went to was haunted buy a old teacher 

Its hard to say. I've dealt with a lot of death in my life through my job and have seen people die in front of me. For whatever reason, maybe I'm imagining it but they always look different, like something is missing (other than.. you know... a pulse)

I'm not a religious person, but I do want to believe in some form of afterlife if only so I don't slip off into a dark empty void, it brings me comfort to believe that maybe I can remain here or maybe be reincarnated somewhere, or sometime else.

Besides it'd be fun to mess with peoples heads from beyond the grave. 

I don't believe in them.

If something supernatural exists, it probably isn't interfering with us or we'd know something about it.

If it isn't interfering with us, does it really matter whether it exists? 

It's not like we'd know anything about ghosts even if they really existed. Chances are they would be something way different from what we have in mind when we say "ghost". 

ive seen a ghost. Was in school building used to be old people house.

Dont believe in them 

Can't say I do but it would be cool if they do exist
