Manatsu no Yoru no Yume

I’d been having nightmares for an entire month, and it was even starting to affect my autonomic nervous system. That’s when a woman calling herself a messenger from the “Mansion of Dreams” suddenly appeared. She said she came from the world of the nightmares that had been plaguing me.

I gave in, telling myself “Even if I refuse, the nightmares will probably continue…” and I accepted her invitation to the mansion. To return from this ‘Hell of Dreams’ to the real world, I had to open every door inside the mansion. “Every answer lies inside of your memories” the girl told me, and then disappeared.

Left all alone, I turned towards the door in front of me.
