It is a fantasy adventure tale about a young girl called Yuuki Wakasa, who one day acquires a magical red stone. The stone allows her to travel to Takamagahara (高天原 "High Plane of Heaven"), the dream world, when she sleeps, and can only return to Nakatsukuni (中ツ国 "middle country"), the real world, when she goes to sleep in the dream.
Yuuki discovers that she must save the sun, Amaterasu, from being trapped and destroyed in Takamagahara, or the light will be lost from both worlds forever. The plot draws elements from the samurai epic Nansō Satomi Hakkenden by Kyokutei Bakin, and from Chinese and Japanese mythology, particularly the Amano-Iwato legend.
The manga has been translated and republished in German by Egmont Manga & Anime from November 2002 to May 2003, and English by Tokyopop from August 2004 to August 2005. The series has since gone out of print.

- All three of the Imperial Regalia of Japan appear in Dream Saga. The mirror Shinjukyou (Yata no kagami) and an additional mirror, the Shinkakyou, open the stairs to Tenjukyu. A sword, most likely the Kusanagi, is retrieved from one of the crystal Orochi's scales. And the magic stones resemble the Yasakani no magatama.
