Many people believe that dreams are a reflection of what is going on in a person’s life at that moment in time. Dreams occur during REM sleep, which is typically 20-25% of sleep time. In some dreams, the dreamer is an observer, even an observer of himself. People often try to lucid dream, or take control of what is happening. They attempt to place themselves in an altered state of consciousness. This can not possibly be true, as there is no physical way to make your body leave and come back. People must train themselves to sleep in such a way where they believe to be controlling their dreams. Instead, they are actually training themselves to subconsciously remember their dreams. They wake up thinking that they controlled the actions that were done in their sleep, but that is not actually the case. People that claim to have lucid dreamt also believe to see “dream signs”. These are up to interpretation and are not actually true to real life situations. Some dreams can seem very realistic but in reality are just as real as the dreamer perceives it to be.
