Becoming crazy in a dream signifies that you are experiencing some extreme emotions. You might be feeling powerful and unstoppable, where the rules apply differently. You might be feeling like you’re on top of the world, or more powerful than reality itself.
A dream where you’re losing control or going crazy indicates that you’re not keeping your focus on the task at hand. You may be more concerned with external factors such as being criticized or being attacked then sitting down to complete a task.
