The Dream World is a place that is only accessible while you have a Pokemon 'sleeping' in a Pokemon White/Black game that has been synched to the Pokemon Global Link.
There are various things you can do: obtain new Pokemon with their Dream World (Hidden) Ability, get items, grow Berries, transfer any items/Berries to your game, decorate your Dream Home, obtain further decorations for your Dream Home, and unlock/select new C-Gear skins, Pokedex Skins, and Musical Songs (only one can be active each).
Island of Dreams
Here you can find Items & Berries and play mini-games with various Pokemon to try to befriend and later obtain them in your White/Black game.
(C-Gear Skins/Pokedex Skins/Musical Songs)
These are actually changed and (usually) obtained from the main Pokemon Global Link page, but some are obtained via the Dream World.
As you earn certain amounts of Dream Points, various things will unlock in the Dream World.
