I think the lines

Put on my raving shoes and I boarded a plane Touched down in a land where the skies were blue In the middle of the pouring rain Everybody was happy Energy shining down on me

are basically a thinly veiled metaphor for doing ecstasy at a rave (the line about the skies being blue in the pouring rain is part of it, so is the everyone happy bit) -- it really makes everything feel perfect, almost no matter what. the boarded a plane bit is probably eating the pill

the bit about a first class ticket probably is meaning he got good stuff, and well yeah...he feels as good as possible.
