Hollywood star Leonardo DiCaprio's attempt to quit smoking was thwarted by repeated nightmares of gory mass murders. The 'Titanic' star has been trying to kick the deadly habit but had to stop using nicotine patches - adhesive pads which emit low dosages of nicotine - after they disrupted his sleep,Contactmusic reported. "When I take nicotine patches I have blood curdling nightmares of murder. Mass murders. I wake up in the middle of the night and have to take them off," said DiCaprio. The 35-year-old actor is unsure whether the nightmares reflect his psyche in any way. "I don't really remember my dreams that much apart from then. I don't know what that means about me from a psychological point of view but that's the truth," he said.
