I had a dream one time that i was grinding on rails that were very similar to that level in SA2....it was...final rush?

If not those, then the rails in Egg Fleet in Sonic Heroes.

I eventually fell, because my plates cracked and fell apart. I fell 1000's of feet and somehow landed near the unisphere half-dead with my quickdraws (thats what i was wearing) destroyed.

My dreams are always 3rd person mode, i dunno why

my dreams are sorta like i'm nailin all my tricks at my spot that i go to soap and right at the end of my dream i for some wierd reason fall off a rail in the middle of doing an acid sidewalk in my black expresses.
