Samenai Yume was definitely an interesting read, if not a pleasing one.
The art is delicate and gorgeous. With the liberal use of grays and black, iit conveyed the dark, eerie tone of the story quite well. This one-shot contains some graphic scenes of sex and gore. However, I thought it added to the creepiness of the manga as a whole.
The length of the one-shot was not enough to give much development to the characters. Despite this and the simple plot, the ending was nicely done. It gave some closure, but left me shivering with awful realization.
Samenai Yume will tickle your mind, depending on how you
read it. It's worth a shot.
