If you are the tightrope acrobat: your serenity is threatened by others. You have lost the ground under your feet! Crashing to the ground: severe emotional conflicts are ahead.
See String.
Depth Psychology: The rope represents your dependence on other people or things. Maybe you are asking others to pull with/or for you.
The acrobat on a tightrope (if the walk is successful) represents inner balancc or (if the crossing is not successful) the lack of it.
If the rope is strung very tight: be more tolerant toward others.
