The direction to which you are looking relates to your viewpoint, whether it be an optimistic one (looking up), a pessimistic one (looking down) or realistic one (looking straight ahead). On a more positive note, this dream may signify a sense of freedom and liberation.
To dream that someone else is standing on a ledge means a friend needs your help. [1]
It is this precariousness that holds its symbolic meaning. To be “on the ledge” is synonymous with being highly stressed and in danger of becoming more so.
A ledge in your dreams is pointing to this state in some arena of your life. Where are you at the very edge of your ability to hold things together? [2]
