"Sweet Dream" is a song recorded by Canadian singer and songwriter Alessia Cara. The song was released on July 15, 2021, as the lead single from her third studio album In the Meantime, alongside the promotional single "Shapeshifter". Cara has stated that the song is about her struggles with insomnia.
Cara began to tease the song on June 28, 2021, before officially announcing the release on July 2, 2021.
Louis Pavlakos of Complex named "Sweet Dream" as the twenty-seventh best Canadian song of 2021, saying "Though the track sounds uplifting and even outright happy at times, Cara just wants to sleep, something we could all use a little bit more of".
The song was performed by Cara from Niagara Falls on The Late Show with Stephen Colbert on July 19, 2021. She also performed "Shapeshifter" on the same day. "Sweet Dream" was then performed on Live with Kelly and Ryan.
