Quick question are your first to second year of college? A lot of colleges do stuff like this to be a pseud filter. Kids who don't know what they want to be when they grow up and choose a degree randomly or people with no passion, but a love of money tend to be trouble for colleges. Those stupid essays are a way to nip that idea at the bud and prevent them from wasting 4 years on a degree that makes them go "I hate this".
I have the same problem too. I don't see my degree as something I should be passionate about, but as a means to an end for money. I'd be ok doing any degree if it made me money and left me enough free time for my hobbies. I've long ago accepted I'd rather daydream about what I hope in life than getting it, so I have no real dream I want to achieve. Like you I just lie when they ask the question
A bit different, but I can't take "how would you survive X", "live in x time period", or live in the wild type questions. I'm diabetic so the answer always devolves to "I would have no insulin if I were at X. I die in a week". You can't stretch that answer out into 3 paragraphs so I just forget I have diabetes and make shit up.
