Madotsuki meets many different and bizarre characters in her dreams, ranging from ordinary people and animals, through frighteningly weird creatures to giant eldritch monsters.
The strange behaviour and expressions of the characters in Yume Nikki seem to exhibit certain personality traits. They influence a lot of the atmosphere of the game, even if they don't actually do much at all.
Many characters play particular role in the game. Some give Madotsuki effects when she interacts with them, whereas others may teleport her to a completely different place. Others may ignore Madotsuki completely and simply loiter in the deranged world of her dreams.
Note: None of the characters, excluding Madotsuki, have official names. All dream characters were named by the fan community, and many characters have not yet been named (See talk page).
These characters give effects when interacted with, although not all effects are received from characters.
