The achievement names in Alan Wake 2 and The Lake House DLC are all extracts from the Return manuscript.

This is something I realised only recently and haven't actually seen mentioned anywhere else e.g. 'Escape its Gravity' is from 'Gail Taken' - "The black hole grinned. Gail couldn't escape its gravity. He worshiped it." and 'His Way Out' is from 'Door Traverses The Dark Place' - "In part for the writer to navigate his prison. In part to torment him as he struggled to find his way out."

What's also cool is that at least one is from New Game+: 'Chased the Source' is from 'Saga Anderson's Deja Vu' - "Somehow, it felt familiar. The straps. The heart. The mutilated corpse laying on the rain-soaked wood. Like deja-vu. She chased the source of the feeling. Found nothing." This page wasn't out at the time of the initial release so it's foreshadowing through an achievement name.

Night Springs doesn't have any that follow this pattern as it's set outside of the main timeframe of Alan Wake 2, but as The Lake House is (being an addendum to Return), the pattern continues for this expansion. For example, 'Fault in the System' is from 'The Marmonts Taken' - "Jules had dangled the painting like a lure and hooked an ocean. Their machines couldn't hold it. A fault in the system. The water rushed in."

It's a nice detail that adds to the feeling of Return taking over reality in the game - it's even taking over the names of the achievements.
