For as long as we've been on earth, dreams have always been a natural part of being human.

According to the International Association for the Study of Dreams, the earliest recorded dream and interpretation in history is from Dumuzi of Uruk, a Sumerian King, who ruled around 2500 BC. Since then we've been trying to understand the concept of dreams and how they fit in our daily lives.

Some of us believe dreams have no meaning at all while some argue that dreams have purpose - they're like psychotherapy, they help us sort through memories, achieve psychological and emotional balance and they help us "practice responses to threatening situations."

What all these theories have in common is that they try to explain why we dream but have you ever wondered what would happen if you couldn't dream anymore?
