Symbolic reading

This represents a period of profound uncertainty in your emotional or life journey. The fog is the ambiguity; the colorless quality signifies that the emotional landscape is currently undefined, lacking sharp focus.

Practical reading

The dream suggests that you are in a necessary transitional phase. While the lack of clarity is stressful, the movement through the fog indicates that forward motion, even without a map, is occurring.

Psychology explanation

The fog is the mind's way of processing the unknown. The achromatic quality suggests that the emotional variables are still shifting, and rushing to define them would be premature.
