Throughout Among the Sleep, you will interact with numerous environmental objects that serve as puzzle elements. These are not items you carry in an inventory, but rather objects you manipulate in the immediate environment to open paths, create bridges, or solve obstacles. Examples include chairs you can climb on, boxes you can push, planks of wood you can use as makeshift bridges, or levers you can pull.

The game's puzzles often involve using your small size to your advantage, such as crawling through vents or under furniture, or finding creative ways to reach high places. You might need to stack objects to create a climbable path or push a heavy item to clear a doorway. Observing your surroundings and understanding how a toddler might interact with everyday objects is key to solving these environmental puzzles. Teddy's light can often highlight these interactive elements.
