Desktop and Documents folder invisible in finder, but visible with ls command As the title said, my Desktop and Documents folder doesn't appear in finder when i'm in the path /users/[username]

But however : 

$ ls /users/[username]
Applications    Qt              workspace
Desktop         Movies          
Documents       Music
Downloads       Pictures
Library         Public


How is that possible ?
This is normal behavior if you have activated Desktop &amp; Documents Folders syncing in iCloud (as @pjc90 has mentioned in the comments).
