What do all the metaphors in jay z's song beach chair mean? i can't figure them all out!!!!!!!!!?

In the song, Jay-Z gives his view on life - as if it were a dream. The general theme of the song is that Jay-Z is in the 'afterlife' of rap. The song is suggesting that Jay-Z is relaxing on a beach chair, whilst dreaming about various issues that reflect upon him. Whilst the melodic notes and strings were produced by Chris Martin, the reverbal drums in the background were produced by Dr. Dre. Some people have quoted that the song is not hip-hop as such. There is a presence of a light kick drum in the background, but it is very faint. Also Features a small guest appearance of Beyonce saying 4 words during the first verse "are you happy Hov".
