To dream of being in a back lane behind houses represents behavior or situations that you don't perceive any danger with. Feeling that there is nothing to stop you from doing something. Noticing nothing interfering with your goals or plans.
Negatively, a back lane may be a sign that you are too comfortable getting away with something.
Example: A young man dreamed of seeing a friend walking towards him in the back lane behind his house and talking about doing drugs. In waking life the young man was hesitant about trying a new drug, but not sure if he'd get away with it.
