The title is from the song "Sweet Dreams" written by Don Gibson made famous after being recorded by Patsy Cline.
Luther Hawkins' dream is a parody of the ZZ Top video of "Legs" and includes the cast of its music video.
One of several St. Elsewhere episodes not included in Hulu's available streaming of the series. Hulu only has 23 of the 24 season 3 episodes available to stream.
The rock song played on Peter's radio in Jack's dream is a soundalike cover of Led Zeppelin's "Heartbreaker".
St Elsewhere often included rock hits in its episodes, but for licensing reasons these were usually soundalike cover versions. The version of ZZ Top's "Legs" in this episode is a rare instance where the original hit recording is used. However, because of residual licensing rights to the music, this episode is very difficult to find on legitimate sources (e.g. Hulu).
