• When asked in 2006 which Weezer guitar solo he is the most proud of/likes the most, lead singer Rivers Cuomo answered, "I'd have to go with 'Only in Dreams' and [Make Believe track] 'Haunt You Every Day' for sheer length. Epic, epic, epic. So few people play these kinds of solos anymore."
•  It is to date Weezer's longest song.
• The song has a prominent bass line played by Matt Sharp which does not resolve to the tonic of the key until the final note of the entire song.
• Only In Dreams has not been played in full since 2015. The middle to end of the song was played after the bridge in King of the World during the White Album tour.
• The song's lyrics tell the story of a young man who wants to be romantically involved with the girl of his dreams. But because he cannot do so in reality due to how nervous he is, he can only fantasize about being with her in his dreams; hence the title of the song. In a 2010 interview with Rolling Stone, Weezer frontman Rivers Cuomo said, "I think most of our audience always thought it was a song about a girl when I’m really singing about my artistic process."
• "Only In Dreams", in recent years, has typically been played at the end of a regular set (before the encore). However this is not true for the Summer of 2002 Enlightenment tour, when the set lists were determined by the roll of a 20-sided die.
