Hey, Jilly. This dream seems to reflect where you feel you are right now in your waking life.
Being barefoot *can* indicate a child-like state but in your case because you felt "inappropriately" barefoot, it more likely is a symbol of poverty or lack, feelings or worries of financial vulnerability. Also, your self-esteem is taking a hit in your waking life.
The fact that you have one shoe on has both positive and negative connotations: The bad news is that without both shoes, you are feeling off balance, off your game. Physically, emotionally and mentally.
However, the good news is that you still have on one shoe so at your core, you have what it takes to make great progress once again.
Do a little bit of dream therapy by using creative visualization. During meditation or just before you drift off to sleep, imagine yourself wearing the newest, strongest, most amazing shoes ever made and see yourself doing a dance, leaping over hurdles, running through beautiful terrain. Feel the wind blowing through your hair as you run and climb effortlessly to higher places to view stunning vistas. Conquer your mountain and feel your reward of being balanced and exhilarated! Breathe. Breathe. Breathe.
