SINKIN' IN THE BRaiN

## Chapters

*-Wake Date Up-*
*"Date's dreamworld... In this strange and surreal dream, trust the light to wake up Date."*
—Somnium description
**SINKIN' IN THE BRaiN** is a dreamworld featured in *AI: THE SOMNIUM FILES* based on the Sagan Residence.

It is a Somnium world created from Kaname Date's dream while napping at the Central Hospital. It acts as a tutorial for Somnium puzzles.

## Mental Locks

### Mental Lock #1 - Turn on the light.

The Somnium begins with a guided tutorial within the room. With the lack of any timer found within the Somnium, there is no penalty to interacting with all optional choices within the Somnium, giving anyone free roaming across the room as long as they don't progress too far.

The only object that can be interacted with at the beginning is the **Door**, and the only option available is *Investigate*. In doing so, the tutorial progresses, as the **Door** becomes inaccessible and the **Light Switch** and the **Winter Iris** become available with the small sliver of light.

Both the **Light Switch** and **Winter Iris** have two possible interactions, but Aiba must interact with the **Winter Iris** first before the **Light Switch** is capable of doing any action. By selecting *Smell*, the **Winter Iris** is removed in favor of allowing access to the **Light Switch**. Select *Turn On Switch* and light flows into the room, removing Mental Lock #1.

In summary, to unlock Mental Lock #1:

* *Investigate* on **Door** -> *Smell* on **Winter Iris** -> *Turn On Switch* on **Light Switch**

### Mental Lock #2 - Open the door.

In the second Mental Lock, three objects are available to interact with: **Standing Lamp**, **Basket**, and **Wine**. Each object has 3 actions featuring optional dialogue, but 1 in each blocks access to that object for the rest of the Somnium. With the **Standing Lamp**, the choices *Lift Up* and *Turn Off Light* are optional, while the choice *Kick* prevents further interaction. With the **Basket**, *Wear Basket* and *Tackle* are optional, but *Search* progresses. And with the **Wine**, *Investigate* and *Smell* are optional while *Take a Sip* progresses.

Progressing with all the objects listed above opens up interactions with the **Skeleton**. Selecting *Kick* on the **Standing Lamp** unlocks the choice *Hit* on the **Skeleton**. Selecting *Search* on the **Basket** unlocks the choice *Investigate* on the **Skeleton**. And selecting *Take a Sip* on the **Wine** unlocks the choice *Talk* on the **Skeleton**. Within this choice chart, most of the actions are optional, but selecting the action *Hit* on the **Skeleton** progresses the Somnium itself and changes the layout, removing access to the other objects and choices around.

At this point in the stage, the **Hidden Item** is available to be located. The game gives a hint of its newfound presence during its tutorial, and the object can be found on the kitchen sink nearby.

After hitting the **Skeleton**, only two objects become available: the **Door** once again and the **Gun**. The **Door** holds new interactions, but none of them progress further. The **Gun**, on the other hand, has the option to *Pick Up* or *Investigate*. By picking it up, the Door can be unlocked. The choice *Put Gun in Keyhole* on the **Door** is the final choice in the Somnium, and selecting it will end the level.

In summary, to unlock Mental Lock #2:

* *Kick* on **Standing Lamp** -> *Hit* on **Skeleton** -> *Pick Up* on **Gun** -> *Put Gun in Keyhole* on **Door**.

If the player is also aiming for the "Protect Your Head" achievement:

* *Wear Basket* on **Basket** -> *Kick* on **Standing Lamp** -> *Hit* on **Skeleton** -> *Pick Up* on **Gun** -> *Put Gun in Keyhole* on **Door**.

## Hidden Item

* The **hidden item** is located on the kitchen sink, available after the room is deconstructed near the end of the Somnium.

## Trivia

* The different occult objects in the basket include a UFO, a Chupacabra, and an American one-dollar bill.
	+ UFO is an acronym for an Unidentified Flying Object, usually associated with alien spacecraft.
	+ A chupacabra is a Latin-American creature of folklore, directly translating to "goat-sucker", which, as the name suggests, is reported to have drank the blood from rural livestock.
	+ The American one-dollar bill has the image of an Egyptian pyramid, with the Eye of Providence situated on the top. The Eye of Providence is usually associated to the urban legend of the Illuminati, the religious organization that oversees governmental faculties around the world.
	+ When investigating these objects, Date states "the truth *is* out there", which is a quote from the American show *The X-Files*.
* The Bansai-Wine bottle has the label "Spike Chunsoft Original Wine", in reference to Spike Chunsoft, the company who made *AI: THE SOMNIUM FILES*. It is currently unknown what the year 1972 refers to, however.
* When smelling the Wine, Date notes that he likes "good drinks and better company." This could be a reference to his hobby of visiting the bar Marble or the cabaret club Tiefblau.
* During Mental Lock #2, executing *Wear Basket* on **Basket** is one of the requirements to obtain the achievement "Protect Your Head." Other requirements are in PSYNCIN' IN THE SUSTaiN and PSYNCIN' IN THE CURTaiN, respectively.
