It was just a dream!
As Tiger said, a dream is just a dream.
I didn't read your novel, way too much to read.
It means you shouldn't eat spicy food just before going to bed.
Plus ... We ARE all going to die.
Sure, you can reflect upon the dream . . . But remember, it is your subconscious letting loose. This can be some nested emotions kept tucked down or just the result of your imagination after Binge watching the first season of "Stranger Things" . . .
At face value, it's a story about your having to do something you absolutely didn't want to do, but could not figure out how to avoid doing before you woke up.
Trump just happened to be the person your subconscious used to be in your dream because you have heard so much about Trump in the news lately.
If that helps you, use it; if it doesn't make sense to you, ignore it.
Dreams are pretty much never predictive of the future. You have a better chance of getting hit by lightening 10 times tomorrow on an absolutely clear day with no clouds in the sky.
