Stage 1

Stage 1 is a stage which is very beginner or the first stage or the lowest stage of sleep. Generally, we can see this stage 1 if we know or realize that our eyes motion is slower than before. In this stage, someone usually will be easy to feel sleepy, but also easy to wake up whenever. Some people who feel or face this stage, they could sometimes get muscle spasms suddenly.
