The Science of Why We Sleep and Dream

The Science of Why We Sleep and Dream is a self-paced learning path in Biological Sciences, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to identify the primary biological reasons for human sleep cycles; describe the internal clock regulating sleep and wake patterns; outline the distinct stages of the human sleep cycle.
