My favorite temple is probably has to be the Spirit Temple. The Temple's music, desert theme and countless epic fights with Iron Knuckles, Lizalfos and the fun battle with Twinrova makes this dungeon very memorable to me.
The scariest Temple to me has to be the Forest Temple followed by the Shadow Temple. While I won't deny that the Shadow Temple is creepy with the disembodied voices, ReDeads, and that room with the Floor Masters it didn't really phase me as much as the Forest Temple, especially since I was able to make quick work of the monsters with the Biggoron Sword.
The Forest Temple, however, terrifies me. The tune is downright creepy, like the melody that plays through a person's mind as he slowly spirals towards madness! The ghosts of the temple also creeped me out as a kid, especially the boss Phantom Ganon pulling his face off like that.
Of course, neither of those can hold a candle to the true face of evil that is the Bottom of the Well....
