What did you dream about last night?
The idea of the left side of anything in a dream will have associations with something that has not been tried before or something different than what you normally do. Since the 'right' is the accepted path, going 'left' shows a new way or new approach 'the road not taken.' See also Arriving and Leaving and Placement and Perspective.
