"Dreams" is a song by Van Halen released in 1986 from the album 5150. It was the second single from that album, and it reached number 22 on the Billboard Hot 100 chart that year. "Dreams" also appeared on the soundtrack to Mighty Morphin Power Rangers: The Movie nine years later, which introduced Van Halen to a new generation of potential fans. It was released in 7" and 12" single formats, the 7" single featuring the album version and the 12" single featuring a slightly extended version.

"Dreams" was written during the Sammy Hagar era of the band. It was performed during most tours featuring Hagar, including the most recent Hagar reunion tour. Even the Gary Cherone-headed tour supporting Van Halen III featured the song in their set-list. The song was also used to close the 2004 Democratic National Convention, played after the acceptance speech of John Kerry. It was also used as the campaign's theme song at rallies across the country in 2004. During an interview with Hagar for Rolling Stone featuring questions from fans, Hagar said that "Dreams," along with "Right Now" were his favorite Van Halen songs, with "Dreams" being his most favorite if you pushed him. The song has also been redone by Hagar by his solo band, becoming a slower, more contemplative song, performed acoustically instead of the original album's faster paced rock arrangement.

Eddie Van Halen played both guitar and keyboards on the studio version of this song. During live performances on the 5150 tour, Eddie Van Halen played the keyboards and would switch to the guitar during the first solo, while Hagar played the rhythm parts until then. On later tours, he would play guitar only, while the keyboard piece was either played "off-stage" by a hired performer (such as Alan Fitzgerald of Night Ranger during the For Unlawful Carnal Knowledge Tour), or pre-recorded material was used. Another interesting note; during live performances on the chorus "We'll get higher and higher, straight up we'll climb. Higher and higher, leave it all behind", bassist Michael Anthony usually sings the second "higher" in both parts, but on the studio version, Sammy Hagar sings them both. This became a standard part of the song's live performances and Eddie Van Halen would also join in the singing.
