Waking up in a strange bedroom in a dream world, teenager Haruto Tsukishiro finds a strange app on his phone. When he activates the program, an odd woman appears and tries to drag him to her realm. Luckily, a mysterious, white-haired girl severs their connection and helps him escape, revealing that the woman is a witch; however, their conversation is cut short. As Haruto enters the realm again, he meets an anthropomorphic, talking cat named Katsumi Kanzaki. While the witch's minions pursue them, the white-haired girl opens a door for them to escape.

After their ordeal, Haruto describes their savior—which only he can see—and Katsumi, the leading authority on dream world research, realizes that she must be "Lily," a being that resurfaces repeatedly across multiple dreamscapes. Hoping to leave the dream world through a blue door, they enter the witch's realm once again. Finding themselves in peril, Lily reveals the truth to Haruto: witches suffer from "Sleeping Beauty Syndrome," a coma-like sleep state induced by torment in their real world lives. Thus, they cannot wake until they are defeated in the dream world.

After finally defeating the witch and locating the blue door, Haruto and Katsumi say their farewells, promising to meet up in the real world. However, when Haruto exits through the door he awakens in the dream world bedroom once more. Seeking answers, Haruto and Katsumi try to uncover the mysteries of the witches, Lily, and Haruto's own inability to leave the dream world.

I saw people giving this a 10 and I disagree. Here's my half-assed review

+ Art can be visually interesting

+ They tried to make it different

- Characters, especially the MC, are inconsistent

- I am not invested in any characters. The mc is to inconsistent and the "witches" aren't given enough time to be flashed out

- Lackluster animation, tons of still shots with minimal movement

- While this show rides itself on being artful and smart, it's "interesting shots" have little to no meaning

- It feels like an edgy teen who really likes Shaft anime wrote this

- I'm a really big fan of Teddyloid, but I don't read more

When your dreams become nightmares.

This is a series, almost more of a series of different stories, though connected by the main char. But so far each story has been different and rather enjoyable.

Story: Witches exist and can control dreams, making you die in real life if you do in the dream, and one boy that tries to help them.

Art: very unique each episode is different and creative.

Characters: so far only a few regulars but each are interesting, especially the chars that are met in each story.

Enjoyment and overall: Only four episodes so far, but read more

I do not understand how this show has such a low score, the only explanation being that people dropped it after episode 1 which I agree wasn't the best.

Episodes 2 and 3 were excellently done though, so hopefully this little review can make you decide to give it another shot.

Story 8/10: This is a very episodic series with each episode being very different from the next. Episode 2 and 3 for example were very serious all the way through, while episodes 1 and 4 had serious parts but also had very cutesy kid like parts which imo pulled away from the messages trying to be read more

The story depicts the event where the MC is saving a lot of witches from their deep slumber. There is a Cat-Head Avatar who is in real life a doctor who has a daughter or sister sleeping maybe a witch too.

First Episode - Seems complicated to tackle down what's the main topic in the series, there is a girl who is claiming herself as the MC's sister. Well let's take aside from that point. This episode shows how the MC fought the Witch's dreams by the power of his dreams. As he finally settle down her, she promised to herself to find him.

Second Episode read more
