U-Turn

Dreaming about executing a u-turn refers to your need of going back to something in your past.
A u-turn symbolizes return, recurrence, repetition, and most of the time it refers to the past. You should probably examine your waking life for whatever has come back to you recently, such as a fight with someone, or having to see that someone you fought with in the past. Taking a u-turn in a place where it is not allowed it means that you do not want to deal with the changes in your life.
