Dreams are an intriguing mystery to us all. In at least one point in your life you have tried to analyze dreams to try to unlock the inner workings of you symbolistic mind. This interpretation has been practiced since ancient Rome and most likely before. However, what do we really know about dreams?

Science knows a whole bunch of what happens when we dream, and interpreters claim to know why we dream what we dream, but here's some fun facts about dreams.

Let's start with the obvious, we forget 90% of what we dream.

It's said that within five minutes of waking, half your dream is gone. Within ten minutes, 90% is gone. This fact is slightly famous due to poet Samuel Taylor Coleridge who woke from a dream to write the poem Kublai Khan, he was interrupted half way through and was unable to finish the striking poem.

Did you know that you can't snore and dream at the same time?

This is widely circulated fact around the internet. No scientist has published any conclusive reports on the matter, however you can read in dept about the theories of skeptics and believes here.

On that note, when we dream our bodies become paralyzed.

When we enter REM sleep, the phase of sleep when we begin to dream, the brain fires a mechanism that causes the spinal cord to stiffen and paralyze our body. This is basically our brain protecting the body from itself. This protocol is to prevent us from acting out the actions in our dream. A good thing too, I'd hate to have my boyfriend acting out his violent action hero dreams while I'm next to him.

That being said, violent dreams are a warning sign.

If you or someone you know does bypass the bodies natural paralysis and they start acting out in their sleep, they may have a disorder called REM Behavioral Sleep Disorder. While this may mean waking up with a few ouchies in the morning, it's an early warning of neurological disease along the line, including Parkinson's disease.

Hate nightmares? Don't stay up late. Day sleepers have more nightmares.

Scientists have not quite put their finger on why, but people who hang out or work during the night and sleep during the day are prone to more nightmares than those who hold the normal sleep schedule.

You wouldn't think it, but blind people dream too.

People born blind don't dream of images, but manifestations of their other senses. If there comes a time where science can show us dreams, it would be interesting to see what they see. People blinded after birth, however, still see images of things in their dreams.

You can only dream of things you know.

That dream where you were in Rome, even though you have never been and you were being swept off your feet by a sassy, sexy young women you've never met. Even though you've never been to the place or met the women, you do know them. Rome is probably pieced together of pictures you've seen throughout your life and that young woman could be the lady that rang up your groceries five years ago. The brain is a funny thing and it can remember even trivial things to use in dreams.
