Dragonflies
As a creature of the wind, the dragonlfy totem represents change. It's iridescent wings are incredibly sensitive to the slightest breeze, and so we are reminded to heed where the proverbial wind blows - lest we run into stormy weather.
Dragonflies are also creatures of the water, and any creature whose habitat is in, or around water carries symbolism relative the the subconscious, or "dreaming" mind and thoughts.
This is because in the animal world, water is symbolic of the subconscious mind ("deeper mind," "dreaming mind") and relates to the thoughts we have in relaxed/meditative/sleeping/subconscious states.
Dragonflies carry messages that deal with deeper thought - and they ask that we pay attention to our deeper thoughts and desires.
