Yes. I see dead people... and there's one right behind you.

Nah.

Casper my friend!!!

Well honestly speaking I didn't until my house was haunted by several, and I keep seeing all different sorts around in inhabited and uninhabited places.

There were 3 types of ghosts I think I have seen in my house. One was a dark blue light which hovered near the ceiling of the downstairs bedroom. It wasn't so much light that it actually produced light but you could see it clearly even though it was night and the light in the hall was off.
The other was a floating white orb which my now ex-boyfriend saw(the orb was hovering in mid air slightly bigger than a tennis ball, a ball of white and the light in the hall was on this time. He could see it clearly), he just about shit himself and didn't want to go back downstaris to get my towel. Btw he's 6ft7 and pretty big, he's also an athiest and believes in nothing.
The other was more of a vortex shape rather than a ghost, it was sighted by my brother and his friend. Who didn't speak of it till half an hour later, they just ran back up to their rooms. But we have constant electrical problems in that room and we constantly get it fixed. Then it comes back again.
Also in the downstairs room there is a power board which we plug a hair dryer into. When my ex and I used to argue it'd turn itself on, even when we turned the board off at the wall it'd turn on. He's physically have to unplug it and bring it with him and continue yelling with it in his hand.
Lights flicker alot and we have had strange calls. Although the strange calls could be anything, my ex claimed he heard his own voice say hello back to him and hung up. But it could have been feeback.

Anyway, it's pretty hard to not convince yourself these are real. It's either that or you have gone crazy.

I can stand by the fact we have had 4 eye witness accounts of this activity. And they were non believers. Some still are.

I can't be, because I haven't really been left alone by them. And sometime it scares me when they can speak. And definately no one is there.

The way I deal with it is I keep living my life and let them go and do whatever they feel the need to do.
e.g: interupt domestic violence, have fun scaring ppl(can't be much to do when you are dead).
