I'm not scared of ghosts because I don't think they exist. I think when you're in the dark and sometimes when you think you see something that's just your mind playing tricks on you.
I'm not really scared of ghosts, but it's kind of creepy if things explode off the wall in the middle of the night...
Long story short, I was sitting at the computer at about midnight and an aerosol can exploded off the wall. At the time though, I didn't know what it was.
I wouldn't say scared but unsettled to say the least. Things that go bump in the night aren't nothing but seeing and feeling things are very different story.
