Question: Disney Dreams! was conceived by the creator of which nighttime show at the Disneyland Resort?
Context: Summer Nightastic!  was an annual three-month promotion by the Walt Disney Company celebrating the summer at the US Disney Resorts.  It started in 2009 at the Disneyland Resort and had returned for 2010 at the Disneyland Resort and at the Walt Disney World Resort.  The event included special nighttime events and ride operations.  Walt Disney World featured events at the Magic Kingdom, Disney's Hollywood Studios, and Epcot.  The Disneyland Resort featured events at Disneyland Park and Disney California Adventure Park.  It was replaced by Disney Soundsational Summer at Disneyland, however the fireworks were retained.  The event did not return to Walt Disney World in 2011 either. Disney Dreams!  was a nighttime spectacular at Disneyland Park in Disneyland Paris.  It was designed specially for the 20th anniversary of the park and ran until 24 March 2017 after which it was replaced by "Disney Illuminations".  Conceived by "World of Color" creator Steve Davison, the show features projection mapping onto the park's castle, fireworks, water fountains, fire, music, lasers, searchlights, mist screens and other special effects.  Since spring 2011, Dreams began testing with original projector animations but, in late 2011, some scenes that were tested in early 2011 were deleted and others were changed.  Using the technique of projection mapping, the castle can be visually transformed in numerous ways such as shrinking, spinning and turrets flipping. The Disneyland Resort Line is a heavy rail MTR line connecting Sunny Bay to the Hong Kong Disneyland Resort, coloured pink on the network diagram.  It is the seventh line of the former MTR network before the merger of MTR and KCR, and the world's first metro line designed to service a Disney theme park.  There are only two stations on this line, Sunny Bay and Disneyland Resort, and the line operates as a shuttle service between these two stations.  Sunny Bay station is an interchange station with the Tung Chung Line between Tsing Yi and Tung Chung stations. Magic Music Days is a program put on by the Disneyland Resort, the Walt Disney World Resort, the Disneyland Resort Paris and the Hong Kong Disneyland Resort.  It brings in school and community groups to perform in the parks and/or take part in workshops or clinics.  Types of groups include: The Art of Disney Animation is an attraction at the Walt Disney Studios Park in Disneyland Paris, Disney's California Adventure in Disneyland Resort and Hong Kong Disneyland in Hong Kong Disneyland Resort.  In Walt Disney Studios Park, the attraction opened in 2002, along with the park, and is located in the Toon Studios Area (previously known as Animation Courtyard).  Toon Studios is where the animated characters come alive - here guests learn about how Disney animated movies are created and can step into the imaginary worlds of animated features from Disney and Pixar. Fantasmic!  is a nighttime show at Disneyland in the Disneyland Resort, Disney's Hollywood Studios in Walt Disney World, and Tokyo DisneySea in Tokyo Disney Resort, that features fireworks, characters, live actors, water effects, pyrotechnics, lasers, music, audio-animatronics, decorated boat floats, and mist screen projections.  The narrative structure of "Fantasmic!" —although varying differently in set pieces in all three versions—centers on a voyage through Mickey Mouse's imagination that culminates in a battle against the Disney Villains. The Main Street Electrical Parade is a nighttime parade, created by Bob Jani and project director Ron Miziker, famous for its long run at Disneyland at the Disneyland Resort in California and Magic Kingdom at the Walt Disney World Resort in Florida.  It features floats and live performers covered in thousands of electronically controlled lights and a synchronized soundtrack triggered by radio control along key areas of the parade route.  The parade has also spun off several other versions that ran or continue to run at Disney parks around the world.  Currently, an updated version runs at Tokyo Disneyland as the "Tokyo Disneyland Electrical Parade: DreamLights".  In 2014, Hong Kong Disneyland premiered a spiritual successor to the Main Street Electrical Parade, the "Paint the Night Parade", which, like its predecessor, features "Baroque Hoedown" as its theme song.  An extended version of "Paint the Night" premiered at Disneyland on May 22, 2015 as part of the park's 60th anniversary celebration. Rail transport can be found in every theme park resort property owned or licensed by Walt Disney Parks and Resorts, the theme park and vacation resort segment of the larger Walt Disney Company.  The origins of Disney theme park rail transport can be traced back to Walt Disney himself and his personal fondness for railroads, who insisted that they be included in the first Disney park, the original Disneyland (a key component of the Disneyland Resort) in California in the United States, which opened on July 17, 1955.  The Disney tradition of including transport by rail in its parks has since been extended to other Disney properties with the opening of Walt Disney World in Florida in the United States, Tokyo Disney Resort in Japan, Disneyland Paris in France, Hong Kong Disneyland Resort in China, and Shanghai Disney Resort in China. Disney California Adventure is a Disney theme park in Anaheim, California, adjacent to Disneyland and part of the larger Disneyland Resort.  It opened on February 8, 2001.  Here is a list of the current attractions found therein, arranged by "land" and with brief descriptions.  These are only attractions from the Disney California Adventure itself, not from Disneyland park or other parts of the Disneyland Resort, and that parades and character meets are not listed in this article.  (The term "attractions" is used by Disney as a catch-all term for rides, shows, and exhibits.)  Disney California Adventure currently has 34 attractions in the theme park. World of Color is a nighttime show at Disney California Adventure, part of the Disneyland Resort in Anaheim, California.  Conceived by Vice President of Parades and Spectaculars, Steve Davison, and designed by Walt Disney Creative Entertainment, the show has nearly 1,200 musical water fountains and includes lights, fire, lasers, and fog, with high-definition projections on mist screens.  The show is inspired by Walt Disney's "Wonderful World of Color" anthology television series, as evidenced by the use of its eponymous theme song written by the Sherman Brothers.
