Can you spot the book, the egg, the cup and the pillow?

At first glance, this bedroom scene seems perfectly ordinary: complete with lamp, bed, and shelves.

However, cleverly hidden in the image are four everyday objects: a book, a cup, an egg, and a pillow.

The challenge? You only have 17 seconds to find them all.

While it may seem simple, this puzzle is more complicated than it seems.

This type of visual puzzle plays on the way our brain filters the surrounding environment.

When objects are camouflaged or placed in unexpected places, our mind tends to overlook them.
