The phrase "Is this the real life? Is this just fantasy" is from which of these songs?

The song by Queen that contains the phrase "Is this the real life? Is this just fantasy" is from the 1975 song "Bohemian Rhapsody". Widely considered to be one of the greatest songs of all time, “Bohemian Rhapsody” was the first single released from Queen’s fourth studio album, "A Night at the Opera". It became an international success, reaching No. 1 in seven countries and peaking at No. 9 in the USA. Seventeen years after its initial release, “Bohemian Rhapsody” re-entered the pop charts in the US, peaking at No. 2 after being featured in the 1992 hit movie "Wayne’s World". In 2002, the song was listed at No. 1 in a Guinness World Records poll as Britain’s favorite single of all time—ranking higher than four Beatles tracks and “Imagine” by John Lennon.

Complex and operatic both musically and lyrically, “Bohemian Rhapsody” (like Led Zeppelin’s “Stairway to Heaven” and The Eagles‘ “Hotel California”) has attracted endless fan theories and commentary. The surviving band members have claimed that the narrative is based on the Faust legend. Music critics have found possible sources in opera and Freddie Mercury’s personal biography; but like any good piece of art, it’s open to several interpretation.
