We dream to fulfill our wishes. In the early 1900s, Sigmund Freud proposed that while all of our dreams, including our nightmares, are a collection of images from our daily conscious lives, they also have symbolic meanings which relate to the fulfillment of our subconscious wishes.

We breathe by contracting our diaphragms, which expands our chest cavities. This allows air to be drawn in inflating the alveoli. Millions of small sacs. Inside our lungs, each of these tiny balloons is surrounded by a mesh of blood-filled capillary in his blood that absorbs oxygen from the inflated. Never mind carbon dioxide.
