The home invasion was the worst.

Erin Wamsley doesn’t want to hear about you dreams. As a sleep researcher and principal investigator at the Furman University Sleep Lab, she gets enough of that at work — not to mention from strangers at parties.

The U.S. boasts 59 National Parks and 117 National Monuments, most of which are overseen by the men and women of the National Park Service. In other words, this governing body makes it possible for Americans to hike, fish, seek solace in nature and sleep by starlight. Next month the NPS celebrates its 100th anniversary. To celebrate, we dug into the history of "America's Best Idea" for sleepy tales and tidbits, and came back with conspiracy theories, whispering ghosts and a contested campfire origin story. Enjoy.

To lucid dream is to be aware you're traipsing through your subconscious. In some cases, lucid dreamers even report calling the shots in their REM-sleep narratives. And while the practice hasn't gone fully mainstream, it has earned props from scientists as an objectively verifiable altered state of consciousness. But, knowing that people can have lucid dreams doesn't translate to knowing who and how many of us are.

When you’re having an I-don’t-care-about-being-healthy day, the type of day when all you want to do is pick up a half-dozen cupcakes from the local bakery “for a party” (they’re all for you) and then proceed to eat them in front of the TV, the last thing you want to see as you’re walking home is some chump in the gym sweating it out on an exercise bike, right? Wrong. The last thing you want to see is that chump on the exercise bike sweating it out whilst reading a book at the same time.
