Why is Sleep Important?
Altered States are the states where our consciousness is altered different from normal.Stage One of sleep is where the brainwaves are slow. This is the lightest sleep stage where a person is easily awakened which lasts about 30 minutes. This is the consciousness stage, where there is a steady stream of thoughts, emotions and perceptions.
Stage Two of sleep is where our body temperature drops and our heart rate slows. This lasts about 20 minutes.
Stages Three and Four of sleep is our deepest stage of sleep, we are hardest to wake at this point.
REM Sleep: is when we do the most lucid dreaming.
Circadian Rhythm: are physical, mental, and emotional behaviors that follow after getting no sleep for 24, which can cause a lot of damage to the human body.
Our preconscious is the thoughts that are unconscious at the moment, but aren't repressed and are easily recalled.
The unconscious mind contains significant and disturbing material that needs to be kept out of the awareness of others because it's threatening.
Selective attention is the particular part of the time we choose objects or choices without thinking about what it can do to you later.
