Nickname 
To dream of somebody's nickname signifies how you feel about that person and the memories you might have shared with that person. An unfamiliar nickname may be a pun or a metaphor.
To dream that a person is calling you by a nickname expresses a desire on your part to change the perception of how others look at you.
Handle
To dream of a handle indicates that you are in the driver's seat of a current circumstance. This dream could also represent that you have control of the circumstance. If the handle is broken within your dream, then you need to get a grip on the person you have become. For this you may need to pool your inner resources.
