I believe in ghosts.....in luigi's mansion.

Aye I believe in Spirits,they're live down isle 4 of my local supermarket.

Nope. I don't believe in anything supernatural. Simple as that.

How could you explain Boos if you don't believe in ghosts?

Oh, if people mean ghosts as in dead people... Naw. Assuming humans have "souls", I see no reason they stay in this world after death. Sometimes when I hear people talk about ghosts, they just mean supernatural spirits and such. I think there's enough unexplainable occurrences in the universe that something such as "familiar spirits" are not impossible. I have never seen firsthand any sort of evidence for supernatural activity in this world but just because I haven't seen it doesn't mean it can't exist. I'm open to the possibility and would love to see unexplainable phenomena, if this sort of stuff is real.

I don't believe in souls, ghosts, angels, demons, karma, or anything else spiritual or supernatural.

I see things pretty similarly to @Capt_N, but the phenomenon of hauntings as we know them today is intriguing. I guess it's how one interprets what is actually happening in a so-called haunting.
Has anyone read the stories about supposed MMORPG hauntings like the Minecraft one? They're pretty entertaining, if nothing else.

I don't believe in ghosts, but I'm not happy that they don't exist. The confirmed existence of the afterlife and the supernatural would be a positive development for me.

Yes but those stories in my opinion are boring. What ever happened to kids gathering around a campfire telling non video game related ghost stories?

Oh yeah, "ghosts" are real. All you need do is bust out the Ouija Board to communicate with them.

Nope.

My house gets a ghost that smokes, yet It turns up at weird times and weird places around the house.
My mum smelt it in my sisters room, this was during the days when we used to go to school and were to young to smoke anyway. And nobody else in the family smokes.
I could of understood if it was a neighbour smoking outdoors and the smell being brought up with the wind, which we thought it could have been.
The thing was, I smelt the cigarette smoke some years later in the middle of the night, in the hallmway of my house. On the 3rd floor between my bedroom and the bathroom. It was just on 1 spot aswell and I couldn't smelll it any where else.
There was another time when my mum had bought a pair of scented candles for the bathroom. They were made where the candles were in champagne flutes.
They were put on the windowsill, one morning, I went to go for a bath and one of the candles had fallen on the and the glass from the flute had smashed.
The window was closed, so it's not as if the wind had blown it over. Even if it had, the wind would have to have been strong to have blown it half way across the room. Plus, the second candle hadn't budged.
About a week later, the same thing happened with the second candle, and that time I heard it fall and smash on the floor.

I don't believe in ghosts. Because there would have to be billions of them. Ghosts of everyone and everything who had lived. Ghosts of cats, dogs, cows, horses, insects, dinosaurs, and cellular bacterium. You would not be able to turn around without tripping over (or tripping through?) hundreds of the deceased.
