Spiritual Meaning:
Extreme suffering – spiritual, emotional or physical – may be perceived as having extinguished or sapped spiritual passion.
Psychological / Emotional Perspective:
Usually extinguishing suggests putting out a fire or a light, having the symbolism of smothering emotions or covering up deeper feelings.
Everyday Material Aspects:
When we dream of extinguishing fire or light it is often worthwhile to look at how this is done. Dreaming of switching off a light suggests that we have cut off a source of energy, with the potential for it to be reinstated. For instance dousing a fire with a blanket suggests suppressing a powerful energy.
