I've had a few.
Several about alton towers
1 - Oblivion had been moved to near Ipswich train station, was still a vertical drop. but was on an individual wiegand alpine coaster style car, which you knealt on, and after the drop there was a big jump.
2 - I was in the queue for nemesis - which had been moved to a different place in the park, and the queueline was really boring
3 - I rode 13, which was in single 2 seater suspended cars, similar to arrow suspended's
, and had a very unusual indoor section.
other park related dreams
1 - Riding skyrush - was good, but not as insane as the real thing
2 - in an arcade in a park, winning a huge amount of money on a slot machine - I think about 27,000 GB pounds!, all paid in 50ps!
