Many people who dream do not understand why they dream or what their dreams mean. I can still remember one particular dream I had as a young child that still puzzles me. I was in my backyard on my tire swing spinning and swinging around. As I was swinging the door on my dad's tool shed started to open up. I then saw things that could only be described as humanoid aliens. They then stepped out, captured me, and took me into the tool shed. The tool shed must have really been a space ship from what I could see inside of it. They were using a cordless telephone, but for what I do not know. Eventually I was rescued by Wonder Woman who flew in and rescued me in her invisible jet. The dream I have recounted may or may not have any significant meaning to me: however, dreams are a natural phenomenon that have fascinated human beings for centuries.

English: Stage 2 sleep. Sleep spindles highlighted...Even though dreams are not fully understood, researchers have documented a number of facts about sleep. For instance, studies have shown that sleep is classified into four stages according to depth as a sleeper goes from a light sleep to a deep sleep. As people fall asleep they first enter stage one sleep. Research has shown stage one sleep to be the lightest of the four levels of sleep. In this stage the E. E. G, a machine that measures types of brain waves, shows many alpha signals. Alpha signals really are fast low voltage brain signals. The sleeper can also be easily awakened while in this stage of sleep. The next level of sleep is stage two. In which the brain shows sporatic brain wave signals which consist of high-voltage activity known
as sleep spindles. Many people have...
