America's favorite science teacher Bill Nye explains how your dreams work.
You know emojis have taken over when scientists use them to explain how things work.
In a new series from Mashable, Bill Nye, America's favorite science teacher takes a look at the science of dreaming.
When you turn off your alarm clock in the morning, your day is just beginning. You're groggy. You're tired. You hit snooze like a million times (if you're me). But you're awake.
Your brain, on the other hand, never went to sleep. It was busy working the overnight shift.

Sometimes you wake up and your dreams from the night before are so vivid. Sometimes they're just straight up bizarre. And sometimes you can't recall them at all.
The average person dreams about four to six times a night, so whether or not you remember them, if you're sleeping, your brain is busy dreaming.
Basically, it's always up to something. One brain would never walk up to another and be like, "Hey brain, what's up?" and receive an "Oh, not much" in response. It'd be more like ... "EVERYTHING IS UP! ALL THE TIME! I'M A BRAIN!"
Or to put the beautifully complex behavior of the brain simply...
Bill Nye has found the perfect emojis to explain just what the heck your brain gets up to at night.

Basically, neurologists say your brain can be found in three states:
1. Your brain is AWAKE!
That's your brain RIGHT NOW! That's why you're reading this! And getting lost in Wikipedia rabbit holes and getting distracted by the Internet and living your life. I can't even explain it more because it's so obvious! You're awake! And your brain is too!

2. Your brain is in a rapid eye-movement (REM) cycle.
This is a fun one. This is when things start to get weird and dreamy. This is the part of your sleep sleep cycle where your eyes start to move rapidly (ha! rapid eye movement! get it??) and your body goes through many physiological changes. Your limbs become limp and your breathing becomes irregular. This, believe it or not, is the perfect condition for dreaming.

3. Your brain is in the non-rapid-eye movement (NREM) cycle.
Non-rapid eye movement doesn't sound as fun because it's considered dreamless sleep, but it takes up more of your life than REM. So you should get to know it.
About 80% of your sleep takes place in NREM. This is when your breathing and heart rate are slow and regular and you are pretty still. This is most likely not the time when you are talking in your sleep or rolling around stealing the covers from your partner. Which they definitely appreciate, by the way.

Nye briefly touches on this, but humans aren't the only ones who experience dreams. Animals likely do too.
Most mammals experience rapid-eye movement, so "it is reasonable to suppose that animals have something like what we call dreams," Patrick McNamara, director of the Evolutionary Neurobehavior Laboratory at Boston University, told National Geographic. That's pretty cool to think about.
Scientists are busy discovering more about how the brain works in humans and in animals.
From the amount of sleep disorders faced every day to the effects smartphones may have when you're trying to get some shut-eye, we're giving scientists plenty of material to work with.
While we wait to learn more, just try to get a decent amount of sleep at night. Netflix will be there in the morning. And besides, you're clearly awesome at dreaming, so DREAM BIG.

An Irish woman went to the doctor for a routine eye exam. She left with bright neon green eyes.
It's not easy seeing green.
Did she get superpowers?
Going to the eye doctor can be a hassle and a pain. It's not just the routine issues and inconveniences that come along when making a doctor appointment, but sometimes the various devices being used to check your eyes' health feel invasive and uncomfortable. But at least at the end of the appointment, most of us don't look like we're turning into The Incredible Hulk. That wasn't the case for one Irish woman.
Photographer Margerita B. Wargola was just going in for a routine eye exam at the hospital but ended up leaving with her eyes a shocking, bright neon green.
At the doctor's office, the nurse practitioner was prepping Wargola for a test with a machine that Wargola had experienced before. Before the test started, Wargola presumed the nurse had dropped some saline into her eyes, as they were feeling dry. After she blinked, everything went yellow.
Wargola and the nurse initially panicked. Neither knew what was going on as Wargola suddenly had yellow vision and radioactive-looking green eyes. After the initial shock, both realized the issue: the nurse forgot to ask Wargola to remove her contact lenses before putting contrast drops in her eyes for the exam. Wargola and the nurse quickly removed the lenses from her eyes and washed them thoroughly with saline. Fortunately, Wargola's eyes were unharmed. Unfortunately, her contacts were permanently stained and she didn't bring a spare pair.

Since she has poor vision, Wargola was forced to drive herself home after the eye exam wearing the neon-green contact lenses that make her look like a member of the Green Lantern Corps. She couldn't help but laugh at her predicament and recorded a video explaining it all on social media. Since then, her video has sparked a couple Reddit threads and collected a bunch of comments on Instagram:
“But the REAL question is: do you now have X-Ray vision?”
“You can just say you're a superhero.”
“I would make a few stops on the way home just to freak some people out!”
“I would have lived it up! Grab a coffee, do grocery shopping, walk around a shopping center.”
“This one would pair well with that girl who ate something with turmeric with her invisalign on and walked around Paris smiling at people with seemingly BRIGHT YELLOW TEETH.”
“I would save those for fancy special occasions! WOW!”
“Every time I'd stop I'd turn slowly and stare at the person in the car next to me.”
“Keep them. Tell people what to do. They’ll do your bidding.”
In a follow-up Instagram video, Wargola showed her followers that she was safe at home with normal eyes, showing that the damaged contact lenses were so stained that they turned the saline solution in her contacts case into a bright Gatorade yellow. She wasn't mad at the nurse and, in fact, plans on keeping the lenses to wear on St. Patrick's Day or some other special occasion.
While no harm was done and a good laugh was had, it's still best for doctors, nurses, and patients alike to double-check and ask or tell if contact lenses are being worn before each eye test. If not, there might be more than ultra-green eyes to worry about.
