Dreams 
To dream that you are dreaming suggests the state of your feelings. You could be too concerned with a particular episode in your life and are working to deal with it.
Lucid Dreams 
Wouldn't it be wonderful to have complete control over entire universe? Would you defeat your enemies? Gain great treasures? Just take a long vacation? Well, all of this is possible within a lucid dream. In a lucid dream, you are completely aware of the fact that you are dreaming, and with a little practice you can take control of what happens in your dream.
There are two types of lucid dreams, those in which you realize that you are dreaming right from the beginning and those in which you realize that you are dreaming only after the events in your dream don't add up to a logical conclusion. It is possible to go to sleep with the intention of having a lucid dream. Some people have been able to train themselves to enter an almost hypnotized state of complete relaxation, moving seamlessly from the conscious to the dream state.
Lucid dreams are also commonly associated with out of body experiences. Have you ever had a dream that you were a ghost? Perhaps you were floating above your body, or you left it behind while you went to visit your sleeping friends or relatives? This is sometimes called astral projection or spirit walking. These dreams are likely caused by a confusion of signals in your brain. Your mind is seeing the dream, seeing what was around you as you went to sleep, but then your mind can also feel that you are not moving in your bed. In order to make sense of these confusing signals, your brain creates a world in which there are two of you, one which is moving and one which is not. These feelings often create dreams of falling or floating because your body has created an illusion of movement without the restriction of gravity.
One way that lucid dreams can be very beneficial is for those who suffer with nightmares. Learning lucid dreaming techniques can help those with nightmares to literally face their fears in a dream state. Battle the monster, confront your tormentor, and end recurring torment. This kind of self-control can also build self-confidence, not just battling the dream monster but also battling real emotional monsters such as anxiety, self-doubt, or guilt. While it may not have been possible for you to identify the meaning or cause of your nightmares in order to overcome them, it is possible to use lucid dreams as a shortcut. To conquer your demons in dream form can alleviate inner turmoil within your subconscious.
Recurring Dreams 
You are standing on top of a building, you enjoy the view, you take a deep breath and suddenly, you jump, falling and falling with no end in sight. You think to yourself, oh no, not this dream again! A recurring dream is often about a situation in which you feel helpless, like falling, being naked, or failing a test. Recurring dreams happen when there is something bothering you, and the problem continues to go unresolved. Many of us feel helpless when a problem continues unsolved for a long period of time.
In order to stop having recurring dreams, you need to identify the problem and help your mind to let it go. Sometimes the recurring dream actually contains a solution which your subconscious mind is struggling to express to your conscious mind. One way to solve your problem is to carefully analyze the symbolism of everything which occurs in your recurring dream in order to decode the message from your subconscious. Ask yourself questions about the dream which you might have initially thought were unimportant details. Where is the building? What made you jump off? Why did the dream end?
Many times, a recurring dream which appears to be the same over and over again actually contains subtle differences. Keep a dream diary and try to record every small detail that you can remember. If you remember any additional detail in your next dream, try to think back and remember if it was the same or different in the dream before. The differences between your recurring dreams can show you which symbols in the dream are more important than others. The symbols which do not change represent the underlying situation. The symbols which do change represent different ways of expressing the solution to your problem. If you can determine what the series of changing variables have in common, you may identify your answer.
Another way to stop recurring dreams is to try to actively change your dream. It is possible to control the actions you make while you dream, and this big change can cause a whole new collection of symbols to occur. For example, in a recurring dream where you are being chased, turn around and face your attackers! Learning their identity and showing your own strength may be just the boost you needed to overcome the anxiety producing this dream.
