The frequency of your brain waves during REM sleep are beta (which incidentally occurs during the waking state as well). These are low voltage, high frequency waves.
Nobody really knows the why, but it seems to be related to learning and emotional regulation. It is known that acetylcholine plays a role in learning. That chemical may be elevated during REM sleep. Sleep seems to help consolidate memories and calm the emotions, and dreaming could very well play a role in that. Sleep tends to work like this. You gradually drift into alpha brainwaves. Usually, you don't dream during initial alpha level sleep unless you haven't had dreams in a while, perhaps because of sleep deprivation. But you may exerience a phenomenon similar to dreaming before you fall asleep. Then you move into theta brainwaves, and then delta brainwaves. There might be an even deeper set of brainwaves. Then you cycle to alpha mode again, but usually also in REM sleep mode. That is where you do most of your dreaming. Then you cycle back through the different levels of sleep, perhaps four to seven times. Up to 1/4 of your sleep is spent in dreams.

No you can't because your growth hormones are mainly produced during sleep, and inadequate sleep during puberty can stunt growth I'm sorry to say.
One method a scientist might use is polysomnography, where a person's sleep is monitored using various measurements such as brain waves, eye movements, and muscle activity. This can provide detailed information about sleep stages and patterns. Additionally, keeping a sleep diary or using actigraphy (a device that tracks movement) can help gather information about an individual's sleep habits over time.
During sleep, different brain waves are produced depending on the sleep stage. For example, during REM (rapid eye movement) sleep, the brain exhibits beta and theta waves, while in non-REM sleep stages, delta waves are prominent. Delta waves are associated with deep sleep and are typically seen in stages 3 and 4 of non-REM sleep.
They don't. A wet dream is what men refer to as the spontaneous disposal of old sperm/semen, usually during sleep. Women can get sexually exited during sleep leading to wetness but this cannot be described as a classic wet dream.
