Objects of Interest[]

PSYNCIN' IN THE CURTaiN is a unique Somnium that follows an extra set of conditions to beat. Mental Locks are cleared at 4 different checkpoints, where an assortment of choices are provided when the conditions are met, and the correct choice unlocks each Mental Lock. These conditions are a number of interactions with Green Objects in the level, usually resulting in the ruination of the object or its green texture.

For simplicity, the required interactions will be measured as Green Points, and enough Points will give access to the checkpoints for unlocking Mental Locks. A total of 11 Green Points are required to beat the Somnium, and the level begins with 1 Point, due to the actions on the Green Door at the beginning of the level. A total of 14 Points can be obtained throughout the level, with only 1 of these points capable of being locked out by other choices, meaning that, as long as there is enough time, the player is capable of obtaining the necessary 11 Points to beat the level.

Green Objects[]

Green Door (automatically activated at the start of the Somnium) – The back door to the Sagan living room, potentially leading into a room in the back. At the very beginning of the Somnium, Aiba's leg knocks into the door, closing it instantly. This action adds 1 Green Point from the start.

Through that, the lights on the lamp turn on.

Tear 24s ?
Attempting to rip the book open will have have it easily split in two, which she drops. Aiba wonders what this would accomplish, and Date states that this would drive Inmate #89 into a corner.

Pot A cooking pot laying on the kitchen stove. A green substance is inside the pot, as steam rises. The two of them wonder if its contents are perhaps green curry, soybean stew, or boiled green juice like a slime. At the last suggestion, Aiba states that a ninja turtle could leap out of the pot.

Aiba states that she wants to "unleash a furious punch" on an inanimate object.
Check 18s ?
Checking the skull will have Aiba note its similarities to the skull that appeared in Date's Somnium, which Date notes used to have a full skeleton.

Kiss Her 18s
Attempting to kiss Hitomi will have a rather nervous Aiba, after some coercion from Date, kiss her on the lips. Date declares that, since Aiba acts as an extension of himself in dream worlds, she is like an alter ego that manifests in Somnia, meaning that he just kissed Hitomi. Aiba shoots him down, but he states that the action made his heart rate rise, and "another part of me too..." Aiba asks that he refrain from letting other body parts rise from excitement.
Talk to Her 12s
Attempting to talk to Hitomi will yield no results, as Aiba continuously calls to her with no response. Date states that she should try responding to her in a "fawning" way, but she refuses.
Touch Her 24s
Aiba asks Date where she should touch Hitomi, and as Date thinks, he continues to stare towards her breasts.... until Aiba suggests her stomach. She presses her hand against her stomach, and notes that her body is "very hard" due to her stationary condition. Date asks her to repeat what she said, which at first she understood to be referring to her "stationary" condition, but eventually she responds with "She's hard?" Date declares that this information is important and that they should keep it in mind from now on..... And after a few seconds, Date states he forgot her condition, attempting to have Aiba state it again. Aiba threatens to crush him with a vise, and he stops making jokes.

Hidden Object[]

  • The Hidden Object appears at Mental Lock #4, once you've dealt with the Red Eye. Once you regain control of Aiba, head to the shelf next to Hitomi and Falco, behind the green barrier. The Object will be resting in the shelf within reach.


  • Inmate #89's Somnium, PSYNCIN' IN THE CURTaiN, is based on the Sagan Residence location, much like Kaname Date's Somnium, SINKIN' IN THE BRaiN. As such, the levels share various similarities, such as:
    • The Winter Iris, and the choices available with it.
    • The light switch covered in thorns, and the choices available with it.
    • The wine bottle on the table, and Aiba's insistence on getting drunk from it.
    • The floral lamp by the bookshelf, and the choices available with it.
    • The skull with the bleeding left eye socket, and the choices available with it.
    • The conclusion of the Somnium, where Inmate #89 is seen standing over the bleeding body of Hitomi Sagan.
  • When reading about Falco's past, Date compares him to Judge Dredd, a character from the comic book series 2000 AD. In this series, Judge Dredd is a law enforcement officer who acts as a "Street Judge," arresting criminals and even executing them for their crimes.
  • When first examining the Pot, Aiba states that a ninja turtle could jump out of the green slime, and various choices make reference to smelling like the liquid smells like a gutter. This is most likely all a reference to the Teenage Mutant Ninja Turtles, in which 4 turtles, after interacting with some green radioactive material in the sewers, gained sentience and trained in martial arts, becoming ninjas.
  • When Aiba drinks the green liquid in the pot:
    • Aiba collapses after drinking it, and Date yells out "Aiba? Aiba! Aiiiiiiiiiiibbbaaaaaaa!!!" This is most likely a reference to the Metal Gear Solid series, in which, if the player character is killed, the Game Over screen will have a character's voice scream out the protagonist's name in the same fashion.
    • Once she wakes up, Aiba states that the liquid tasted like "elephant" while smiling at Date. This interaction appears to be a continuation to a joke that occurs in the chapter Day 2: Saturday –saikAI–, where Aiba tells a joke in which an elephant is stored inside the Sagan Residence's refrigerator. The refrigerator next to the pot has its door wide open, with the contents inside being empty, implying that the pot with green liquid had just been removed from the refrigerator.
  • Wearing the Pot on Aiba's head will have her comment on how it increases her defense, a reference to wearable armor in RPG games and their defense-boost capabilities.
  • Throughout the Somnium, Date makes several references to his sexual stimulations to various actions that can be done. Most notable is when interacting with Hitomi, in which all 4 interactions with her results in some variance of a sensual/sexual response, such as an erection.
  • Hitomi is the only interactible object in the Somnium that does not contribute to proceeding to any Mental Locks, as it is the only object that is not green.
