What are some of your favorite songs that mention fear or something you fear in the title or lyrics..?

Blue oyster cult's don't fear the reaper-voltaire's goodnight demon slayer-voltaire's brains-voltaire's beast of pirate's bay-creature feature's corpse in my bed-carmen's monster in the house-wheneve i feel afraid from the old musical anna & the king of siam-and there's a metallica song...about nightmares...and another one about nightmares & alien abduction by blink 182 that i used to listen to all the time....drawing a blank....can only remember tune & feeling...aggh! i fear i'm losing my memory!
