There is the following statement in the Haṁsadūta: "One day when Śrīmatī Rādhārāṇī was feeling much affliction because of Her separation from Kṛṣṇa, She went to the bank of the Yamunā with some of Her friends. There Rādhārāṇī saw a cottage wherein She and Kṛṣṇa had experienced many loving pleasures, and by remembering those incidents She immediately became overcome with dizziness. This dizziness was very prominently visible." This is an instance of confusion caused by separation.
Similarly, there is a statement describing confusion caused by fearfulness. These symptoms were exhibited by Arjuna when he saw Kṛṣṇa's universal form on the battlefield of Kurukṣetra. His confusion was so strong that his bow and arrows fell from his hand, and he could not perceive anything clearly.
