Dreaming of the lungs symbolizes the basic essence of life and your life force – as your ability to breathe is most closely linked to your ability to sustain physical life. The lungs also suggest environmental toxins (physical and non-physical) that may be hindering your growth and development. Further, dreaming of lungs can represent ideas of suffocation – as in a relationship with a significant other, parent, etc… This dream symbol can also represent ideas associated with the breath, such as “catching your breath,” and “bated breath.”
