Lucid Nightmare is about a little girl, "Lillian", caught in her own dream. She has to escape her nightmare with her loyal companion "Soctopus". Soctopus is Lillian's mascott, that is alive in her dream. Lillian can use Soctopus as a weapon against "shadows", creepy and scary figures that give lillian bad dreams. Lillian is very scared in the dark. She therefore collects fireflies to give her company and shed a little light in the otherwise very dark dream.
