NCT Dream - ISTJ

Hop in your time-traveling ambulance - we're headed to MBTI World... in your brain! NCT Dream enters through through a creepy neon clown in an abandoned hotel parking lot. They fly over a cool hedge maze (the neural pathways... of your brain!) and land in a hospital-slash-psychiatric ward. I can dig it, mostly because the place is extraordinarily well-stocked with books. NCT Dream reads up on various personality types (but mostly ISTJ, let's be real) and eventually breaks out of the brain, back to the abandoned parking lot Phew!

Ah, yes. MBTI (Myers-Briggs Type Indicator), the psychology personality test that's used like the zodiac these days. ISTJ types ("Introvert...Sensing...Thinking...Judging...", as Mark so helpfully tells us) are known as Inspectors
Movie references: Back to the Future (obviously) and, oddly enough, Brainscan (the weird doctor reminds me of The Trickster)
Mark has an entire stuffed animal sewed onto his jacket
Funniest line: "Yo so hot. Hot like soup" (Jisung)
Boys with books! Haechan (studying "You-Ology"), Jeno throwing books (bad!), Renjun hanging out in the library and Jisung checking titles
MVP: Renjun, for his books & sparkles and smooth dance moves. Honorable mention to Jaemin, who I wanted to see more of in this video
