A feeling or fear of being challenged somehow.
Feeling held back or encountering an obstacle in real life, or a fear of such.
Trying to solve a problem can represent a desire for a real-life solution; feeling stressed; being in “problem solving” mode (perhaps due to your activity earlier in the day); experiencing extra energy during the dream state.
Consider also whether this could have been a Toxic Dream, which often involves dealing with a stressful problem.
