\"Propane Nightmares\" is the second single from Australian drum and bass band Pendulum\'s second album In Silico. It incorporates elements of the song \"Million Miles from Home\" by German Happy Hardcore band Dune. A music video was also produced themed around a religious cult closely resembling Heaven\'s Gate, in particular depicting the mass suicide of members of a cult by poison after first drinking citric juices. Several scenes of Pendulum performing before the cult are intercut in the middle of the video, which otherwise focuses primarily on two members who attempt to flee during the cult suicide.
