Known as "shower thoughts," these random moments of "eureka" are what your mind spews out when you're in the shower, letting your mind wander freely.

Maybe they're not always the most world-shattering concepts and ideas (and usually they're a little bizarre or sometimes pretty disturbing too), but they can change the way you look at the world, and are fun to think about, if nothing else.

They also happen to be one of the internet's favorite sources of both random humor and wisdom. A good shower thought can enlighten you in a way you never expected. It can also leave you sufficiently creeped out to the point where you have to turn the computer off for a while.

But it's not like that's ever going to happen, so get ready to browse some of the most profound or concerning thoughts people had at random times and felt the need to share. Take a look at some of our favorites here.
