This was the disastrous reboot of the popular Journey into Imagination dark ride.
It was a shortened version of the original ride, and inexplicably omitted the two rides two popular characters Figment and the Dreamfinder.
Disney received quite a bit of backlash for the character omissions and this version of the ride only ran from 1999-2001 and then was replaced with the current Journey into Imagination with Figment.
The newest version brought back Figment, but Dreamfinder has yet to return to Epcot.
