I hear thunder from the mountain   Trying to split my personality   I see burning on the hillside   Darkness till the break of day      The wind that blows   A dog that bites   Recurring dreams   Another night      Underground through the marshes   Got to keep the hounds at bay, I know   Can't move, my feet are frozen   There's a pounding in my head      The horn that sounds   I'm through the door   My body's trembling   Turn on the light      Is the mirror lying?   I must decide   If I'm Dr. Jekyll   Or Mr. Hyde      Is the mirror lying?   I must decide   If I'm Dr. Jekyll   Or Mr. Hyde      Is the mirror lying?   I must decide   If I'm Dr. Jekyll   Or Mr. Hyde      Is the mirror lying?   I must decide   If I'm Dr. Jekyll   Or Mr. Hyde
