Well, I do have to agree with you on all of your points.
Like I said, this was merely an experiment to get people to think about it. I didn't put any clear efforts into the film other than it truly was a trip to the park that I captured and then edited. While I like Barnabas' explanation, if I had to pick someone who was "correct" it'd be yours, because that is really all that happened.
The reason I asked for interpretations mostly is this theory I've been working on (whether I actually bring it up in my next English essay is to be seen as the professor has made no indication of writing about anything interesting).
Last year my AP English teacher did what most high school teachers do, and that was have us search for the symbolism in every last detail of the text. It was her idea that even punctuation held great meaning. While that may be true in a lot of cases, not every author puts their periods where they do for art, sometimes it is simply for structure in order to construct a correct and interesting sentence. The same is said for when she'd brown townyse the plot.
But then, that's the theory. Art is within the eyes of the beholder as soon as the artist lets go of it. His official explanation no longer has to mean anything because as soon as everyone has seen it it takes on its own life. Art transcends the artist, as while the artist will eventually die, art itself can be nearly eternal.
So the point of this film, really, was to take a mundane day at the park (with some pretty cool shots o the sunset and other things) and add a bit of artistic flair through editing. Everything you saw in those shots are all chronological; I didn't change the order of the clips when placing them on the timeline. Then I asked everyone to interpret it and see what they come up with.
I was hoping there'd be a few more responses before I explained what it was I was doing (because even I admit this film holds no true meaning nor does it try to even ascend to it), but alas like you said, Creativity is a slow board.
The only counter argument I have to say to you, and this is more in relation to the song than the film itself, is that to me "dust in the wind" is a connection the the phrase "ashes to ashes, dust to dust" which is the idea that when we die, it doesn't matter who you were in life, in the end it's all the same matter being put in its grave to turn to dust (or if you're cremated, ash). The song goes on and says (paraphrasing) "in the end, that's all we all are, dust being blown away never to be seen again." To me, that is existential, as the idea that nothing truly matters, it's your own life and you need to live it accordingly as in the end, we're all turning to dust.
