The opening to the Dream World.
|Located||Within Luigi's subconscious.|
|First game||Mario & Luigi: Dream Team|
The Dream World is a major location that appears in Mario & Luigi: Dream Team. It is where Mario meets Dreamy Luigi for the first time. In order to enter the Dream World, Luigi must sleep on a special type of pillow which then can open the portal to the Dream World. Mario (or any other character) can then jump through the portal to enter the 2-D version of that level. Also, Dreamy Luigi also appears whenever Mario enters the Dream World to aid him in his quest.
