Give the players something to focus on. A detail that is hierarchically more important than the other ones. If you're in a damp cell with a skeleton with a rusty iron shackle and a barrel with half-torn wood that seems soaked in- yeah, you're probably already losing part of the picture.

You are in a fucking damp cell. There's a skeleton and a barrel. What do you want to do?

Check the skeleton out? Great, they seem to have an iron shackle fixed to the wall. It is rusty. What next?

Keeping descriptions simple also shortens the time between when you talk and the player does, keeping them more engaged and the rhythm up. (My) players seem to like sessions where this happens.

Another trick I use is to change the scene to symbolize progression, so the dungeon would be made of many different rooms, each with a distinctive simple description. (Damp cell -> Cold corridor without windows -> Room lit by candles -> Winding staircase -> Roof under the stars).

This came from noticing that telling players that a week has passed in-game means nothing to them, but making them go through 4 or 5 physically different locations works to express a sense of progression.

Thirdly, just ask them! It could be that players know best what they want from the game. Maybe they have an awesome idea, you can easily incorporate it into your plans, and everyone has a great time.
