A ladder in our day to day life is used for reaching higher levels and higher ground. The location of the ladder in your dream and what it is used for will help you to determine what its latent meaning is. If the ladder is upright you could be given a message regarding an upward mobility in your social status, relationship, or perhaps your work or career situation. If the ladder is on the ground, or lying down, you may see other clues in your dream that will tell you what is needed to move it upright again.
You may need to go and get a ladder in your dream for something. This suggests that you need additional tools and resources to move upwards to the place you want to be in life. Sometimes a ladder is also a way out of a precarious situation. Details such as this and the ones surrounding the ladder in your dream will help you to determine what its latent meaning is for your life and specific situation
