Heroin
To dream of the drug heroin represents feelings of emotional addiction or dependency that's dangerous about obsession or euphoria with liking how perfect an experience is. Believing that something perfect is so good that it's difficult to live without once you've experienced it.
Negatively, dreaming about heroin may represent emotional addiction to a perfect experience. An inability to be objective or critical about negative aspects of an enjoyable experience that is too perfect. Perfection that you can't resist or is dangerously difficult to cut off once you experience it. Pleasure or optimism overrides your good judgment. Risking serious losses because you can't separate your need for experiencing perfection from objective reality. Addiction to pornography.
Example: A woman dreamed of being a heroin addict. In waking life, she was accused by her boyfriend of being obsessed with talking about her new job abroad. In this case, being a heroin addict may have reflected awareness of herself being emotionally addicted to the idea of her job making every last thing in her life perfect to the point that she had difficulty talking about anything else.
