Clothing in dreams can represent the role you play in life and how your identity undergoes transformation. Clothing can represent the attitude or the Persona which becomes the mask you wear to fit in.
Dreaming of a sock can represent how you insulate yourself on your path. Wearing shoes without socks shows a more natural approach or attempt to be more connected to your path. You can ‘sock something away’ and dream of a sock as a portrayal of the need to feel more financially secure. See Clothing and Makeup.
