It provides the basis for certain identifications, such as the medieval one: the cave referred to the human heart as the spiritual "center." The cave, in this case, represents the unconscious, your subjective world, the experiences and knowledge accumulated over the years. All this allows you to reach maturity. It is very common dream during adolescence. The events happening inside the cave will reveal which aspects of the Self you are working on. In other interpretations, the cave represents the womb or female sexuality. What you find in it will be those elements the unconscious wants to cultivate in your: virtues, ideas, attitudes, etc. Many dragons and monsters from mythology lived in caves guarding a great treasure. This symbolizes that before winning the spiritual reward, you must fight the unconscious' fears. The cavern may also represent memories about a traumatic childhood that have been banished from conscious memory.

Types of sleep
There are two types of sleep that most of the humans undergo - REM and NREM. REM refers to the Rapid Eye Movement and NREM refers to Non-Rapid Eye Movement. Every individual will alternate these two types of sleep. Non-REM sleep will occur for a short period of time in the first stage of your sleep followed by the REM sleep. Dreams occur during the REM stage, where it lasts for 20 minutes. According to a researcher, J. Allan Hobson, dreams that occur in REM stage are usually forgotten when the individual wakes up. Studies conducted on patients during sleep shows that the frontal lobes in the brain, that are responsible for storing information, are inactive during the REM stage, which is the main cause for forgetting the dreams. Studies also show that this is the stage where you have the most intense dreams.
