No, the movie wasn't real, but something like this can happen actually.
Spirits are fascinating. :3 I lived in a house with 2, one was a baby and one was its mother. [They died actually around 1873 so I read by the entire town catching fire]
I was only 8 and when I saw shit moving like my door, my toys, my tv turning off and on and not being able to get out of the room, it scared the crap out of me. After I moved out, the house caught fire. Creepy.
If people don't believe in spirits I suggest you get a list of "haunted" places of your area and go there when it says to, mostly at night, you'll see at least one thing moving without anyone being there. :3
My friend lived in Maryland and I told him about this street, if you drive past it around 11 or so, your car will automatically stop and your tires will get slashed. [A girl got her tires slashed right before she got murdered]
Just a fyi: no you can't see most of them, some you can though.
another fyi: yes you can hear them faintly.
even more of a fyi: when a spirit is near you, you do get cold.
Oh, and lastly THEY'RE NOT CALLED GHOSTS.
