How can a metaphor affect a persons emotions?

Answer 1

In my opinion, at an emotional level there is no such thing as a metaphor or simile. If I say something is "like kicking a dog" my listener immediately goes to that image and responds emotionally to it. A public speaker can generate the emotion he or she wants from an audience by the choice of simile or metaphor. Consider:

"Drinking from someone else's glass is like shoving your tongue in their mouth."

"Drinking from someone else's glass is about as dangerous as shaking hands."

or

"A nurse who steals a patient's medication is a vampire."

"A nurse who steals a patient's medication is a prisoner of addiction."

Answer 2

Metaphors can evoke strong emotions by creating vivid mental images that resonate with the person's feelings or experiences. By comparing an abstract concept to something concrete and relatable, metaphors can help convey complex emotions in a more accessible and impactful way. This can lead to a deeper connection with the message being conveyed and a heightened emotional response.
