Answer: A SIXTH SENSOR
The feeder answers for this meta are:
ONI ORBS
QUI-GON JINN
SPIRIT PHONE
There are three sets of rows of lights on the left with arrows pointing to three more rows of lights, each row having a partial enumeration given. The left enumerations match our three answers, with the ghost symbols corresponding to the words JINN, SPIRIT, and ONI. These words all indicate types of ghosts; upon considering the right enumerations, we can find a phrase relating to each feeder answer matching that enumeration, where the ghost symbol corresponds to another ghost word:
| Feeder answer | Related phrase |
| QUI-GON JINN | THE PHANTOM MENACE |
| SPIRIT PHONE | LEMON DEMON |
| ONI ORBS | YO-KAI WATCH |
Googling some of the ghost names together or perhaps noticing "phantasm or phobia" in the flavortext reveals that these are all the names of enemy ghosts encountered in the horror game Phasmophobia. In the game, there are seven types of spectral evidence, which the rows of seven lights and the flavortext indicate are important. In the game, players don't know what ghost they are fighting in any given run, and must identify them using spectral evidence, as each ghost is detectable via a unique combination of three evidence types. The purpose of the feeder answers is to identify which of the seven lights corresponds to which evidence type; with enough feeders, it can be determined that the order is: EMF Level 5, Ghost Orb, Spirit Box, Freezing Temperature, UV Light, Ghost Writing, D.O.T.S. Projector.
This evidence can be used to identify a ghost for each row of lights in the final array:
| Evidence 1 | Evidence 2 | Evidence 3 | Ghost | # |
| EMF 5 | Spirit Box | Writing | SPIRIT | 1 |
| EMF 5 | Orb | D.O.T.S. | RAIJU | 19 |
| EMF 5 | Freezing | Writing | SHADE | 9 |
| Orb | Writing | D.O.T.S. | THAYE | 24 |
| EMF 5 | Orb | UV | OBAKE | 20 |
| Orb | Freezing | Writing | REVENANT | 8 |
| EMF 5 | Orb | D.O.T.S. | RAIJU | 19 |
| Orb | UV | D.O.T.S. | BANSHEE | 5 |
| Orb | Freezing | UV | HANTU | 14 |
| EMF 5 | Orb | D.O.T.S. | RAIJU | 19 |
| EMF 5 | UV | D.O.T.S. | GORYO | 15 |
| EMF 5 | Spirit Box | Freezing | THE TWINS | 18 |
These ghosts each have a numbered entry in the in-game journal:
Using the ghost numbers to index into the alphabet gives is this puzzle's answer, and what Shayden is building to aid in their ghost hunt: A SIXTH SENSOR.
Well, it did until the developers of Phasmophobia decided I had it too easy, and released an update less than a month before this puzzle was released. Update 0.15.1.0 added three new ghosts; those new ghosts didn't immediately break this puzzle, but what did break the puzzle was the resulting rework of the journal.
As a result, I received a few DMs from solvers who were confused on how to extract, and a hasty note was added. Always check your datasets before release, kids.
