early part with him hiding seems like that, and the alien lights are just plain old spotlights
take the ending at face value and he's going to the heavens - either getting merc'ed by feds or abducted by aliens. or committing suicide. take your pick. given the ADD mentions and the fact that this song is pre-...whatever this is, from back when big pharma/teachers/feds were just starting to label everyone with disorders and trying to drug everybody, good chance of it being feds merc'ing him bc he learned too much, covering it up as a suicide, and then blaming his ADD on it (complete bs, but obviously the media buys that up and everyone ignores it when literally every family member/friend/love/etc tells the world it's bullshit).
speaking of music with suicidal themes to it though
