Sleep Stages and Dream Interpretation
Five Stages of Sleep
The stages of sleep were first described by Alfred Lee Loomis in 1937, and his coworkers who separated the different sleep stages using an EEG (electroencephalography) which revealed five levels of sleep. Typically everyone passes through five stages of sleep each night
- Stage I is a light sleep or you drift in and out and can be easily aroused. Often during this stage people will experience sudden muscle contractions preceded by a sensation of falling.
- Stage II is a little deeper sleep where eye movement stops, and brain ways become slower with only an occasional burst of rapid brain waves.
- Stage III is where the brain waves are extremely slow, and they are called Delta waves, but they are interspersed with smaller, faster waves.
- Stage IV is where the brain produces Delta waves almost exclusively. Stage III and IV are both referred to as deep sleep or Delta sleep. It is very difficult to wake someone during deep sleep. There is no eye movement or muscle activity in deep sleep.
- REM sleep: Dreams occur during REM (rapid eye movement) sleep, and the rest of your body is a temporarily paralyzed at this time. During dreaming your eyes are moving rapidly; your heart beats faster; you breath accelerates; blood pressure rises, and areas of your brain that you use for learning are stimulated. Brain waves during this stage are actually increased to the levels experienced when a person is awake. Most people experience 3 to 5 intervals of REM sleep each night.
Dreams, REM Cycle of Sleep
Rem (rapid eye movement) sleep typically occurs after you have been asleep for approximately ninety minutes. REM sleep only lasts for approximately ten minutes, but this sleep cycle occurs throughout the night.
Your eyes do move rapidly during REM sleep, but not in the other sleep stages. While babies spend 50% of the time in REM sleep, but adults only spend 20% of the night in REM sleep.
When you are not in REM sleep your heart rate slows and your body temperature drops. This is when you are going into a deeper sleep.

Process of Dreaming
Dreaming is a thinking process but on a much deeper level. Your conscious mind has slipped away, and you are very focused. Plus, you are totally honest with yourself as you figure out your life issues.
What is actually happening is you are moving information from your short-term memory to your long-term memory, so it helps us solve problems, solve information and also to organize our thoughts.
Research has shown that if we constantly interrupt dreams in an individual that they will become psychotic and start seeing hallucinations, even if they get the rest of their sleep. Dreaming is essential to good mental health.
If we were not paralyzed during dreaming, we would be physically acting out the dream. For some people this mechanism doesn't work correctly and oddities like sleepwalking occur, but sleepwalking is more common in deep sleep. Some studies say you can't dream while snoring, but others have not found that to be true.
Dreaming is a natural function of every mammal and bird on earth. If you own a dog you have probably seen them when you're dreaming. Interestingly enough, dogs show the same physiological cycle as humans, having REM sleep, so it is assumed they are having the same type of dreams.

Benefits of Dreaming - Summary
There are several benefits to dreaming. Dreaming will give balance to the events that happened to you during the day, and the more we sleep the more we will be able to integrate things that we learned during the day. Our bodies repair themselves while dreaming, which improves the quality of our life.
Mental, spiritual and emotional coping mechanisms help us develop creative solutions, and new ways of thinking about our challenges, questions and problems in life are another benefit of dreaming.
It is usually easy to tell if you have not slept enough as the symptoms are irritability, mood swings, and falling asleep as you're driving home from work or maybe at your desk. It is your body's way of telling you to turn off the lights and go to sleep.
