Why does Alisa feel she cannot come home after dark if the porch light is on?

The belief that the porch light attracts frogs, which in turn causes discomfort and a feeling of not being able to breathe, suggests a specific and personal association that Alisa has developed with the light and the presence of frogs. This may indicate that she has an underlying fear or aversion linked to the situation. Phobias or specific fears can often stem from unique personal experiences, leading individuals to develop beliefs that may not seem rational to others. Alisa's reasoning implies that her anxiety is directly connected to what she perceives will happen when the porch light is on, illustrating a psychological phenomenon where irrational fears coalesce with specific stimuli, leading to avoidance behavior.
