In Chapter 3’s Akeley Memorial Hospital route, talk to all three brains in the Wireless Room, then enter 13 → 05 → 36 on the frequency machine, validating each entry before moving to the next. Completing the sequence rewards Dream Essence.
Where to find the Wireless Room puzzle
The puzzle is in the Wireless Room on the Akeley Memorial Hospital route in Chapter 3. Interact with all three brains before using the frequency machine. The room also contains an E.R.C. Activator Pen, which is relevant to nearby hospital progression but is not needed to work out the frequencies.
Wireless Room code
- Set the first frequency to 13 and validate it.
- Set the second frequency to 05 and validate it.
- Set the third frequency to 36 and validate it.
Use the machine’s validation step after each value rather than entering the full sequence without confirming the individual frequencies.

How the frequency clues lead to 13, 05, and 36
First frequency: 13
Ambrose Pence links the primary frequency to bad luck on Fridays, pointing to 13.
Second frequency: 05
Round 13 to the nearest ten to get 10, then halve it: 10 ÷ 2 = 5. Enter it as 05.
Third frequency: 36
Add the first two frequencies and double the result: (13 + 5) × 2 = 36.
