Bottom of the Well

Once your a kid again, return to Kakariko Village and play the Song of Storms in the windmill. Now enter the dried-up well. This area is very tricky and easy to get lost. Follow the map and numbers below:

1) Continue until you meet what looks like a dead end. Pass through the wall.
2) Enter this wall to get Key #1.
3) Enter here to get Key #2.
4) Take a hidden side route to get to the Compass.
5) Play Zelda's Lullaby here to lower the water.
6) Light the back left torch to get Key #3 in the coffin.
7) Fall through the center hole and explore the bottom area to get the map.
8) Defeat Dead Hands to get the Lense of Truth.

Now go back to the Temple of Time and warp to 7 years in the future so that you are an adult again.
