You are ready for your bed now, but there are no beds in space. A sleeping bag is attached to one of the walls of your cabin with bungee cords instead. Without the need to support your body and head against gravity, you sleep vertically in space, not horizontally. You poke your arms through the holes, and as you relax, your hands float out in front of you, resembling a marauding zombie. Some astronauts find it difficult to sleep like this, so they fold their arms or tuck them inside the sleeping bag. You can shorten the cords to be more tightly bound to the wall. Others enjoy the freedom of floating around the cabin during their slumber, although you might bump into things and startle yourself awake. Being trussed up also means it takes longer to free yourself if you need to make a trip to the bathroom at night.
