Yeah, the extraterrestrial morse code you are talking about is pretty close to what I thought when I listened to this middle section. From 0:44 to ~1:00 to me sounded like an AI bot making some internal configurations after waking up from a long sleep.

Well, and 1:14-1:22 then energetically felt like an entire robot army battle crying whilst marching into the city to conquer Humanity :)

But we each have our own imagination :)
