A teenager with the ability to enter other people's dreams. When he witnesses a dark spirit taking people's lives in their dreams, he quickly realizes that it's related to the mysterious deaths that are happening in the real world.

A terrible incident occurred in Yogyakarta. The victims were found hanging upside down. No one knows who did all the murders. My name is Respati. I have a strange ability, namely being able to enter someone's dream just by touching the dreamer's skin. I was used to this ability before I met Wulan, whose dreams I couldn't penetrate. It was from Wulan that I knew that I was a Dream Explorer. I also knew from Wulan that all the murder cases were closely related to my abilities.
