There are three ways that sleep is measured by using, EEG- Electroencephalogram, EOG- Electrooculogram, and EMG- Electromyogram. In order to measure sleep they use EEG, EOG, and EMG to categorize the sleep stages. As we sleep we hit four different stages of sleep. The first stage is stage 1 EEG or initial stage 1 EEG which is described as a low-voltage, high-frequency signal that is similar to, but slower than that of alert wakefulness. During the progression from steps 1, 2,3 and 4 there is a slow increase in EEG voltage and a drop in the frequency of EEG. Stage 2 has a slight higher amplitude and

One is a Freudian theory in which he stated that dreams are unacceptable repressed wishes, which is why most of them are of a sexual nature. Sigmund Freud believed that in order to deal with a persons psychological problem, we must first try to expose the meaning of the persons latent dreams. Unfortunately, there is no evidence for the Freudian theory of dream. The second is called activation-synthesis theory which states the during REM-sleep the brain-stem circuits become active and they bombard the cerebral cortex with neural signals. I personal believe that the Freudian theory is a bit more believable or understandable to me. In many of my dreams I dream of wishes, or dreams of what I would love my life do be or uncompleted goals that ether I have yet to full fill or regret due to the failure of completing it. So I do think that dreams are vivid images of what repressed wishes we have yet to complete or repressed unacceptable wishes. I am sure that if we can analyze or comprehend our dreams we would have a broader insight in who we are.
