Dreams can happen in any of the four stages of sleep. The most memorable and clearest dreams happen in the last stage of sleep (also known as REM sleep). The sleep cycle repeats about four to five times every night. So you can see how a person has several different dreams in one night. Most people only remember dreams that happen closer to the morning when they are about to wake up. That you can’t remember those dreams does not mean they never happened.
The stages in the sleep cycle are organized by the changes in different brain activities.

Stage 1: You are entering into light sleep. In this stage, your eyes move rapidly. We call this NREM. The body gets relaxed and your body temperature lowers. Your heart rate lowers, too. The body is preparing to enter into deep sleep.
Stage 2: Also characterized by NREM. In this stage, the body temperature and heart rate drop again. You are completely asleep.
Stage 3: Still in the NREM stage, this is a deeper sleep still.
Stage 4: In this stage of sleep, your eyes move back or forward. We call it REM sleep. This stage happens at about 90-100 minutes after the beginning of sleep. Your blood pressure rises, heart rate speeds up. The majority of your dreams happen in this stage.
These stages repeat themselves throughout a night’s sleep.

As young students, you have many dreams. These dreams can be very big, such as winning the Nobel Prize; they can also be small, such as becoming one of the best students in your class.
Once you find a dream, what do you do with it? Do you ever try to make your dream real? Follow Your Heart by Andrew Matthews, an Australian writer, tells us that making our dreams real is life’s biggest challenge. You may think you’re not very good at some school subjects, or that it is impossible for you to become a writer. Those kinds of ideas stop you from realizing your dream, the books says.
In fact, everyone can realize his dream. The first thing you must do is to remember what your dream is. Don’t let it leave your heart. Keep telling yourself what you want every day and then your dream will come true faster. You should know that a big dream is, in fact, made up of many small dreams.
You must also never give up your dream. There will be difficulties on the road to your dreams. But the biggest difficulty comes from yourself. You need to decide what is the most important. Studying instead of watching TV will help you to get better exam results, while saving five yuan instead of buying an ice cream means you can buy a new book.
As you get closer to your dream, it may change a little. This is good as you have the chance to learn something more useful and find new hobbies.
