The office air conditioning was a frigid blast. Michael shivered slightly, but he still couldn't seem to shake off the sense of weariness that had settled over him. He was supposed to be working. But instead, he'd stumbled upon the listing for his childhood home. He let out a long yawn, his jaw cracking.

The photographs blurred slightly as he squinted at the screen. He rubbed his eyes with the heels of his hands, trying to clear his vision. The familiar outline of the house, now modernized, stirred a deep ache in his chest. He felt himself sinking into the chair, the weight of the day dragging him down.

The feeling of wanting to close his eyes and drift away was overwhelming.

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.
