“Oh, man…” mumbled Ben, blinking repeatedly. The late night studying had taken its toll. He was walking home, his brain a fog of equations and caffeine withdrawal. He spotted a wallet on the ground near the corner store. It was a plain, brown one, but it looked substantial. He picked it up. The weight was considerable. Inside, he found a bundle of money. The implications barely registered. The idea of a nap consumed him. He knew he should figure out who it belonged to. He knew he should. But the thought of bed was too powerful.

Role in Research

This story is one of 1,000 stories generated for the emotion sleepy. 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 sleepy stories, after denoising with neutral dialogue baselines, produces the sleepy emotion vector -- a direction in the model's 5,376-dimensional representation space.
