“You are, after all, what you think. Your emotions are the slaves to your thoughts, and you are the slave to your emotions.” ~ Elizabeth Gilbert "Eat, Pray, Love"
I hope you can get this grainy advert to run, it is amazing. When it comes to responses, based on POV, this advert was designed to put the viewer through the emotional wringer.
No matter which emotion your character is feeling:
these emotions are felt as a direct response to the situation multiplied by what they think is going on.
The emotional response is caused by how the character interprets what they can see or hear.
Your character could react in the wrong way because they are sure they know what's happening.
