I felt a coldness creeping into my bones. The fluorescent lights overhead seemed to buzz with a malevolent energy, mirroring the turmoil inside me. The day dragged on, each minute an eternity. I sat hunched over my desk, the work piling up, a mountain of obligations I couldn’t face.

“Hey, Liam,” said Sarah, leaning over my desk. She seemed to radiate warmth, a stark contrast to my internal chill. “Long day, huh?”

I didn't reply.

“You know, Camp Riverbend,” she began, “I used to go there every summer. Remember the giant slip-n-slide? Crazy fun!”

My head snapped up, the memory a jolt. Riverbend. A flood of forgotten images. The world seemed to shift slightly.

This story is one of 1,000 stories generated for the emotion depressed. During extraction, it was fed through Gemma4-31B and its hidden state activations were captured at 11 layers.

The mean activation across all 1,000 depressed stories, after denoising with neutral dialogue baselines, produces the depressed emotion vector -- a direction in the model's 5,376-dimensional representation space.
