There is a really stupid, idiotic and insane enemy in Zelda games called a WALLMASTER. It falls from the ceiling and if it grabs you, you are brought back to the beginning of the dungeon.
I used to be uber scared of them, but now not really.You have to keep on running. It will stop, meaning it is about to fall to catch you, you just run away, when it comes down, ATTACK!
Holy Crap I just beat Link To The Past and had to deal with him. I hate when u are moving a statue and he grabs you only because you have no where else to go
