There is the following statement in the Hamsaduta: "One day when Srimati Radharani was feeling much affliction because of Her separation from Krsna, She went to the bank of the Yamuna with some of Her friends. There Radharani saw a cottage wherein She and Krsna 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 Krsna's universal form on the battlefield of Kuruksetra. His confusion was so strong that his bow and arrows fell from his hand, and he could not perceive anything clearly.
