Dreamcore at 11:30

Concept art style, extremely spacious room. Everywhere in the room, there are entrances and exits that lead to somewhere. A pillar stands in the center of the room, and a long staircase is built winding around it. Pale blue light, shimmering like ripples on water, water lighting, with blue and purple as the dominant colors. A space that evokes unease, as if it could extend infinitely. Nostalgic, dreamcore, liminal space.
