Somuniiru

Our heroine has found herself strangely connected to the world of dreams after an experiment with the Somuniiru system knocks her unconscious. Warned by her professor, who is doing studies on group subconsciousness, she finds herself with the ability to dream lucidly, with one exception - a relic of her first dream during this effect, an erotic outfit made out of a bracelet and long single piece of cloth (and nothing else), seems to be following her around the dream world. But she doens't worry about that, as she has free reign of her dreams now.

But as the strange outfit begins to appear on her in real life for brief, fleeting moments, our heroine is discovering that her dreams might just have free reign of her, too.
