Try "reality checks" throughout the day. Ace your reality check. Gradually build up to bigger activities.

A reality check is when you ask yourself: "Am I awake, or am I dreaming?" This will ultimately help you tell the difference between the dream world and reality when you are asleep.  Reality checks call attention to a fundamental difference between dreams and reality: in dreams, states are fluid; in reality, states stay the same. In dreams, text will change into different words; trees change color and shape; clocks tell time backwards instead of forwards. In reality, text stays the same, trees stay rooted in the ground, and clocks move clockwise.  A good reality check to perform, both in reality and dreams, is looking at text. Suppose a poster in your room says "Justin Bieber." Turn away for a minute, and look at the poster again. If it still says "Justin Bieber," the reality check says that you're awake. If you turn away, then look at the poster and it says "Selena Gomez," the reality check will tell you that you're dreaming. When you're having a dream and realize that you are having a dream, then you start to be able to control most of what happens in your dream.  When you make the leap and realize you're dreaming, try to calm yourself down. If you get too excited about finally being able to control your dreams, you might accidentally wake up from excitement. Try small activities at first. Again, this is about staying in control of your excitement and not accidentally waking up. Even mundane things like cooking food, climbing a ladder, or skateboarding can be fun when you realize you're in full control. A lot of people enjoy flying, swimming deep into the ocean, and time travel. Try moving huge objects, passing through walls, or even telekinesis. The dreams that you can have are limited only by your imagination!
