Dream Leaf

Dream leafs are consumable items introduced in Golden Sun: Dark Dawn. They play a central role to a sub-plot in Kolima, which must be completed to advance the game.

After clearing the Phantasmal Bog, players can purchase dream leafs from a vendor in Kolima. Dream leafs cost 600 coins each, and can be sold for 450 coins.

Plot significance
When eaten, dream leafs grant a person good dreams. They are harvested from the Dream Tree in Kolima, making dream leafs a local specialty, although they've acquired much popularity in Border Town. Unfortunately, prior to Matthew's arrival in Morgal, the Dream Tree had grown ill, tainting new dream leafs so that they produce nightmares rather than pleasant dreams. As a result, the people of Kolima had stopped selling dream leafs until a cure could be found.

Matthew's party came to Kolima hoping to acquire a Roc feather, but soon found themselves aiding the locals with their problems. A citizen of Kolima took the young warriors to the base of the Dream Tree and gave them some dream leafs, hoping they could find a way to cure the Dream Tree. Matthew and his friends eventually drifted off to sleep, and soon found themselves in a dreamworld. After navigating the eeire swamp, they engaged a creature in battle. As soon as the creature was defeated, the heroes awoke in Kolima. With the source of the disease eradicated, the heroes were able to cure the Dream Tree with a bottle of Hermes Water, given to them earlier in Port Rago by Briggs.

Uses
Dream leafs are used to enter a "dreamworld" in certain towns. If anyone in Matthew's party has a dream leaf in their inventory when staying the night at an appropriate inn, the innkeeper will ask Matthew if he wants to use the dream leaf. If the player chooses to use the leaf, Matthew's party will be taken to the dreamworld. A portal appears where the player entered the dreamworld, and entering that portal will cause Matthew's party to wake up.

As of Dark Dawn, dream leafs can only be used in two locations: Kolima and Border Town.
