Traditionally, a lark in a dream is a symbol of transcendence from the worldly to the spiritual. If you dream about a lark, it can be a sign that you are focusing too much on small details and day to day matters; you need to look at the big picture.
You may dream about a lark when you have so many responsibilities that it is hard for you to think about anything other than getting through the day.
Your dream is a reminder that there is more to life than just surviving. You need to take some time to reevaluate your goals and plans. Think about your emotional, moral and spiritual development.
Hearing a lark sing in a dream is associated with good luck. If you dream that you hear a lark sing, your dreaming mind is telling you that there is hope for success in your future
