You are running through the woods and a bear is chasing you, when all of a sudden you wake up in your bed and realize it was just a scary dream. Our nightmares can sometimes feel super scary, even if what’s happening isn’t real.
Fear is a natural part of being a human. In fact, you may have even felt shaky or sweaty after waking up from a bad dream. It’s all part of something we call the fight or flight response.

You aren’t alone if you’ve ever heard someone at the dinner table say, “you’ve got to eat your broccoli.” Broccoli is one of nature’s superfoods, so it’s no wonder we are often encouraged to eat those little green trees.
When I got your question, I met up with my friend Hans Van Dongen, a scientist at Washington State University in Spokane. He works in a research lab where they study sleep. As a cat who appreciates naps, it’s one of my favorite places to visit.
