The world swam into focus, then out again. Arthur shifted, feeling the insistent ache in his lower back that spoke of an uncomfortable night. He’d gone to bed late after binge-watching a show, and now every atom of his being was screaming for more rest. The light from his phone, which he'd been using to check the time, burned a searing spot into his vision.

A series of loud thumps on the front door startled him. His head throbbed as he shuffled to answer it. The tow truck driver, burly and impassive, simply pointed. "Your car," he grunted, gesturing to the empty space where Arthur's SUV had been. Confusion quickly morphed into frustration. "But… it's my driveway," he protested, the words coming out as a weary complaint. The driver just shrugged, unmoved, as Arthur watched his transportation vanish in the pre-dawn gloom.

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.
