If you dream that you are standing on a ledge, you are feeling tense, anxious or excited about something.
Consider what direction you are looking in as you stand there. 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.
