A manual describing which things and how you need to interact together to progress during Somnium segments and also the locations of hidden things.

It’s not an entire guide right now, since I have not finished the game myself, but I will update it as I play.

Day 1: Friday – SINKIN’ IN THE BRaiN

• Door – Investigate
• Winter Iris – Smell
• Switch – Turn On Switch
• Standing Lamp – Kick

I suggest you also try to wear the basket. As far as I know it is related to an achievement.

• Skeleton – Hit
• Gun – Pick Up
• Door – Put Gun In Keyhole

The hidden item is in the sink. Not sure about when it appears, but I collected it just before I picked up the gun.

Day 2: Saturday – PSYNCIN’ IN THE PaiN

This path unlocks Mizuki cured route (meikAI).

• Shoko’s Photo – Pull Out
• Control Room – Open
• Left Bird Cage – Lift
• Torn Paper – Piece Together
• Panda Ride – Stop
• Mizuki – Hug Her

This path unlocks ??? route (keitAI).

Haven’t discovered it yet in my playthrough.

The hidden item is lying on one of the benches. Just pass the control booth and you should see it a little bith further ahead.

Day 3: Sunday – PSYNCIN’ IN THE VaiN

Coming soon.

Day 4: Monday – PSYNCIN’ IN THE SWaiN

This path unlocks Mizuki’s route (syougAI).

• Icy Floor – Lie Down
• Oil Drum – Roll
• Power Board (Look for it at the far back.) – Throw Something
• Ota – Encourage

This path uncloks Ota’s route (jikAI).

• Icy Floor – Lie Down
• Plate (Closest on the right side) – Breathe On
• Forklift – Sortie
• Ota – Motivate

The hidden item is behind the green shelves. You’ll need to approach the ideal side , turn towards the wall and you also should see a tiny enclosed area between the wall amd the shelves that are green. Follow along it till you hit a dead end. The concealed item ought to be appropriate there.
