What is one thing that has made you believe in ghosts?

Question

So what was one (Or more if you want) thing that has made you believe in ghosts?

Answer 1

I don't really believe in ghosts, but there was this time (a time when I did believe in ghosts) I was spending the night at a friend's house. The house is over 150 years old, and was rumored to be haunted. That being the case, I never wanted to be by myself.
One night, we were playing video games (Mario Kart, to be exact), and after not-too-long I realized I was the only one awake. Being as late as it was (almost 5am), and against my instincts, I decided it was time to call it a night and turn off the TV -- the only source of light in the room.
I laid down on the couch, and not a minute later I heard this strange buzzing sound, followed by "BONG! BONG! BONG! BONG! BONG!" It turned out to be just the grandfather clock, but it still scared the crap out of me.
After I calmed down and started to get comfortable, I started to feel a tingly feeling in the back of my neck & on my head -- my hair was standing up. Seconds later, I hear a strange moaning sound coming from the foot of the couch. The sound oscillated kinda like a siren, but it was off-key, almost like an opera singer imitating a police siren. I looked at where it was coming from, and there was nobody there. Had there been, I would've seen their sillouette against the window. It lasted for about 30 seconds, and I just pretended to be dead the entire time. I still don't know what that was.
