Okay
for some reason
our family moved into my schools gym (which has rooms for the coaches)
my room is one of the coaches room, and it has a couch for me to sleep on
and a tv that I watch

One night i'm laying on the couch watching tv when the door to the room suddenly cracks opens a bit
I got up to shut it
this happened 3 times
on the 4th time I got up to close the door
right before I got to it, it opens all the way and a ghostly figure is in the doorway
So I run back to the couch to hide under the covers
but when I get there, anther ghost appears and starts chasing me
I run out of the room, and out of the gym with the 2 ghosts chasing me
they stop at the gyms doorway
but I keep running
Outside I stop and turn around
there is another ghost
but this one doesn't chase me, he seems nice
and somehow I knew his name, and called out to him
but he faded away

-later on in my dream-

I finally walk back into the gym when school had started
and there where tons of kids in the gym
the friendly ghost I had seen was there
he wouldn't talk to me
but he gave me a cookie (I dont know why he gave me a cookie)

Ghosts can be a representation of "ghosts from the past." Is something from your past "haunting you?" Did you like gym class?

The part where you turn and face a ghost and it disappears indicates that you are willing and able to face up to whatever may be "haunting you," then and now.
