"Nights into Dreams... (trademarked NiGHTS into DREAMS...), is a video game released by Sega in 1996 for the Sega Saturn video game system. The game's story follows two children entering a dream world, where they are aided by the main character, Nights. Nights was developed by Sonic Team, with Yuji Naka as producer and lead programmer, and Naoto Ōshima as the character designer and director. The developers' intention was to make the sensation of flight the central gameplay element,[1] achieved through 3D graphics and a combination of both 2D and 3D gameplay. The game was re-released for PlayStation 2 on February 21, 2008 exclusively in Japan.[2] An HD version is planned for release in Fall 2012 for Microsoft Windows, PlayStation Network and Xbox Live Arcade."

"Spring Valley, called The Ideal at the beginning of the game, is the first dream of Claris Sinclair in NiGHTS into Dreams."
