Psych, Chapter 3

There are four levels of sleep. The first two are called light sleep. The last two are called deep sleep. During deep sleep, it is very difficult to wake the sleeper. You don't dream as much in light sleep as you do in deep sleep. 
I thought the Theories of Dreaming were interesting and surprising. Your mind tries to make sense out of everything that you think about and have learned. dreaming also helps you work out problems that you might have and were not able to work out while you were awake. Your mind also puts together situations that you a lot a feelings about.  
I did not find any part that I disagreed with. 

General reflections

The mind is an amusingly complex organ that is capable of many things.
