5. Random Signals

Our brain relies on electrical signals to let it know what is happening around us. Once it has processed these signals coming from the body, it will then send signals out itself, helping our bodies to act accordingly to whatever is around us.

With so many signals flowing through the body at any one time, it is understandable that these will sometimes become confused. Some people believe that dreams are simply an interpretation of random signals that are flowing through the brain. This might explain the often-random nature of the dreams that we do experience and the way that they can suddenly change course for no apparent reason.
