Socks often indicate the intestines and colon in particular.
Since socks cover your feet they can also indicate your ability to move forward with regard to the subject matter of the dream. For example, in her dream, a woman was about to put away laundered clothes when she noticed a trail of black socks, all in pairs, leading out into the back garden. Through this the dreamer is asked to adopt a new attitude (put away clothes) with regard to relationships (in pairs) as she goes forward in life (socks). In particular she needs to eliminate (back garden) the ongoing effects (trail leads to where she is) of negative relationships (black pairs) in the past (back garden).
