To act "dully" means lacking excitement, interest, or brightness. It suggests a state of being uninspired, monotonous, or lackluster. Think of a cloudy, gray day with no sunshine, or a repetitive task that makes your mind numb. It's the opposite of being sharp, vibrant, or engaging. It often implies a sense of boredom or indifference. Imagine a conversation that just plods along without any spark.
