Usually I have no problem with people believing with ghosts, until recently my superstitious housemate started annoying me. You see, she's convinced her room's haunted. She doesn't dare sleep with the light off. Her room is the only one with a light on at night, and because my house is an old house, and the walls let light shine in through small slits , I get light shining on my face every night. As a person who prefers complete darkness to sleep, this irritates me.

I've talked to her about her irrational beliefs, but she's still convinced her room's haunted. Even though the people who stayed in that room before never complained about ghosts or spirits.

I'm surprised that so many people voted Yes to believing in ghosts. I bet many of you who voted Yes are religious, yes? And I'm quite surprised at the lack of knowledge of basic physics. Thus far there is no concrete evidence for ghosts. The arguments I've read so far for the possible existence of ghosts are based on pseudo-science that sounds more like science fiction than experimentally verifiable theories.
