The 4 Stages of
Have you ever wondered what you do when you
sleep? Did you know that you have 4 stages of sleep?
- (Stage 1) This first stage is very light
sleep. If you are not disturbed during this stage you will quickly

- (Stage 2) You start thinking of images, even

events that happened during the day.There are many theories about
why dreams happen. It's not only your eyes that move fast, but
your brain works faster too! Not everyone recalls their
