Dream about a lost shoe states past, forgotten, or lost love. You may be feeling emotionally wounded and are trying to cover/shield your hurt from others. You have a skewed perspective or outlook on things. Your dream is a clue for a self-destructive behavioral pattern. You do not let the comments/criticism of others get to you.
A lost shoe dream points to protection from some negative force in your life. You have not accomplished what you wanted. You should not waste time with petty things in your life. This symbolises distress that will come in the disguise of happiness. You need to break your problems up into smaller conquerable chunks.
If you dreamt about a lost shoe:
While sticks and stones may break your bones, words can also cause a fair bit of damage. So whether you are talking, or find yourself on the receiving end, you will need to handle yourself with great care. You have the opportunity today to actually make things work out very well, but you will need to draw on all your diplomacy. Avoid digging into your stock of swearwords.
