The Hypnos Cabin looks like an old-fashioned prairie house. It has mud thatched walls and rush roof. Red poppies cover the door. Inside there's a fireplace, soft violin music playing, and the air smells like fresh laundry. It makes people extremely sleepy. Above the fireplace there's a branch from the poplar tree from the Underworld, dipped into the river Lethe. It drips Lethe water into tin cups. There are lots of empty beds with feather pillows, fresh sheets and fluffy quilts. The Hypnos cabin often makes people very sleepy, so be warned before entering.
