A pilot makes his way through a dark abandoned spaceship that comes alive: lights flicker, gravity shifts, bulkheads slide

Prompt

Massive abandoned spacecraft, drifting, silent, until sudden partial reactivation creates unstable, shifting internal conditions.  
Docking approach: small ship attaches carefully, everything still. 
Entry: interior dark, debris floating, no gravity. 
First change: lights flicker violently, sections powering up unevenly. 
Floor shift: gravity slams back on in one section, throwing everything down. 
Corridor movement: bulkheads begin sliding, layout changing in real time. 
Near-trap: path closes behind the pilot, forcing a sprint forward. 
System surge: doors opening and slamming unpredictably. 
Pressure breach: one wrong turn leads to a sudden decompression blast. 
Escape run: pilot navigating a corridor that’s actively reconfiguring. 
Final moment: ship barely undocks as the entire structure begins moving under its own power. 
Claustrophobic, mechanical instability, constant “wrong place at the wrong time.”
