Why+do+you+dream?

Why do you dream? Scientists still do not know why we dream. Although, there are many theories. (If you want to read more about some of them go to [] ) Some say dreams occur during REM*. This is the time that our brains are the most active, so it's also when our dreams are the most vivid. When we dream, it allows the stimuli that happens when we are conscious to be clear when we are unconscious. Stimuli or stimulus are actions that cause activities or responses. Some say that dreaming is a good way for us to release unexpressed stress. It is also a way that we refresh our brains. A lot of times, we overwork our brains during the day and when we sleep, we can regenerate it.

Nightmares As most people know, a nightmare is a scary dream that happens during REM. Some people think that nightmares only happen to children, but that is not true. In fact, 5 out of 8 adults experience nightmares. However, there is another kind of nightmare that only children experience called 'night terrors'. Unlike nightmares, this happens in between the stages of sleep. During this, the child heart rate and blood pressure goes up. The child might even get up, or scream and thrash in their beds.
