Hidden objects puzzles have fascinated people for generations. They test not only how sharp your eyes are, but also how quickly your brain can separate what’s familiar from what’s cleverly disguised. At first glance, everything seems perfectly normal until you start to really look.

Below is a photo of what seems like an ordinary bedroom scene, but that’s just at first glance. If you look further, you may notice some objects that don’t usually belong there. What is obvious is the soft lighting from a bedside lamp and the neatly made bed. So, nothing unusual, right?

Truth is the photo hides more than meets the eye. Somewhere within the picture are four everyday items: a book, a cup, an egg, and a pillow.

Now, the challenge is simple: You need to try and find those objects in 17 seconds.

If you believe this is an easy task, think again.

Focus your eyes, and start searching, but remember: once you spot the first hidden object, you’ll never look at the photo the same way again.
