Do You See a Lake or a Wall In This Photo?

The recent obsession with optical illusions has meant it has become difficult to trust your own eyes.

And the latest brain confuddler created by Playbuzz proves that things are not always what they seem.

The image appears to show a beautiful scene of a lake, with mountains in the distance. But can you spot what is really going on?

If you look extremely closely you'll see that the landscape does not include a lake.

It is in fact a concrete wall obscuring part of the scenery, with the shrub growing on the other side.
