What is a Dream?

A dream happens every night numerous times as you sleep, there is series of images, ideas, emotions and sensations. The average person has 3-5 dreams but some have 7 every night. Nothing is certain what they actually mean but philosophers have researched and came up with theories throughout history. Scientists have said that all mammals dream, but other animals such as birds or reptiles is uncertain.

Dreams manly occur when you're at your REM mode of sleeping. This is because your brain activity is high and this causes it to resemble or being equivalent to being awake. At this stage of sleep when you dream, these tend to be the dreams you remember when you wake up.
When you wake up and don't have any recolition of dreaming, those are different stages of sleep but ththese ones are less vivid and not as memorable.
When you dream it can be anywhere from a couple seconds to 20 minutes.
Dreams usually last longer as the night continues on, and if you get a full 8 hours of sleep, your dreams will occur during your 2 hour REM stage. And if you wake up any time in this REM stage you will remember your dream.
Your dreams range anywhere from exciting, frightening, magical, adventurous or sexual.
The events that happen in your dreams are usually beyond your control meaning.
But there is something called lucid dreaming and this is when you're self-aware of what's happening.
Dreams can give a person a creative thought or sense of inspiration.
