Dream Shrine

It is unknown if Dream Shrine's main chamber was a real place or not, even by Koholint Island's standards. The doorway to the shrine is blocked by three large stones, and Link will be unable to enter until he has claimed the Power Bracelet. When he enters the shrine, it appears to be a small room with a single bed. However, if he goes to sleep, he will wake up in a large room. This room is guarded by large groups of enemies, the legendary Ocarina along with 50 rupees can be found here. To get to these items may require use of the Pegasus Boots. After leaving the room, Link will wake up in the bed found in the first room. The Dream Shrine was located on the imaginary Koholint Island from Link's Awakening.

Trivia
It is possible to reach the chest that is filled with 50 rupees without first obtaining the Pegasus Boots if one is skilled enough.
