THis was a WILD ride, lets start from the beggining
The first part sounds like ancient TV, you see how many tv programs about science have this bive of "almost a nursery ryme, but also very mistiique and it makes you wonder more?" is that, in those first notes i could see Jeremy as the protagonist of a TV program (or like Grand Ilusions in youtube/BilNye the Science Guy/ Beakman [WOLRD BEST SCIENTIS]) and he like decenst with a parasol in a lovely pond, the TV he uses to explain thing comes out of the water over a lylypad and he like...explain nature and biology and wholesome stuff (Like Mr. Rogers).
Then it comes the RAVE part, i feel that would be the outro, and it would be super messed up, like a masked figure that looks oddly similarto Jeremy cleaning up bodies and putting all the TV's and furniture in place, cleaning it all to the most miniscule detail.
the break into the 8-bit part feels like the start of another segment of the show, like a pixelated Jeremy completing various minigames to build up a lab where he'll later explain science stuff.
the lasst half is what turns everything 180, that scream and the music goes back to the more moved part, i cant really say what happens there, but the children are happy after it and it comes back to the happy tune, maybe he finally freed himself from something and its finally able to get away, but the nightmare is not done yet, that disturbed noise atthe ned, Jeremy looks at the camera, is this truly a smile or a mask?
