I noticed this a while back, but I didn't have a forum account. In Will's intro, after the camera pans down to the football field in the beginning, it cuts to a shot of some kids kicking around a ball in the foreground (right at 0:17), with a familiar character to the right of the frame, closest to the camera.
Yo, that's straight up Mr. Edwards. Looks like he mastered basketball and has moved on to another sport. It's a cool easter egg, but it definitely doesn't match up with the timeline, as there are only perfect dreamers every 100 years, and since it's likely that Journey happens before into Dreams, there's no possible way that could be Elliot himself. Maybe his grandfather?
