Zelda: Ocarina Of Time Master Quest Part 49: See The Unseen

Conserve as much Magic Power as you can in this dungeon to use the Lens Of truth often. There's a lot of invisible things that can hurt you and/or trick you into getting stuck. Don't be fooled!

Also, a trick with Deadhand is that if you use the Lens Of Truth, you can tell where it'll pop out of the ground at when a hand grabs you so you won't have to gamble to take a hit. Try it out if you have the MP for it for fun.

Enjoy!
