Wow. Reading, that counts as another (4th) Sonic dream. Because you still dreamed about a character from that game; Shadow.
I then looked at a spherical jungle gym thing with red bars.
That made me think of that show, Recess, where there is a half-spherical jungle gym. I don't know, I'm kinda lost for words about this one.
But I think the dream means that you miss hanging out with your friends, and maybe even school (did I just say that?).
There were these cheerleaders doing practice in the middle of the hallway, jumping around with flags and such.
One word; Awesome.
The other night I had a dream that I was at an E3 event and I saw Shigeru Miyamoto on stage. And then he went back into the lobby and I talked to him about Mario. Then he walked me home. ([wtd]?)
Heh heh, that shows how much you (and everybody else) admire Mr.Miyamoto.
PS I didn't have a dream today.
