After immersing yourself in Leonardo DiCaprio’s recent blockbuster film “Inception,” you probably need some time to figure out the intricacies of the plot’s elaborate dreamscape. I know I did.

Here are lots of “Dream” songs to keep you company while you try to sort out the movie’s multilayered levels.

We’ll start with two of the all-time greatest voices:

• Patsy Cline’s “Sweet Dreams (Of You)”

• Roy Orbison with three great songs: “Dream Baby (How Long Must I Dream)” and two featured in movies “In Dreams” (“Blue Velvet”) and “Dream (When You’re Feeling Blue)” (“You’ve Got Mail”)

And here are a couple more movie “Dreams”:

• “Pieces of Dreams,” a Michel Legrand song from the like-titled movie, performed here by Johnny Mathis

• “(All I Do the Whole Night Through Is) Dream of You,” from “Singin’ in the Rain”

Then a pair of songs by two legendary singers:

• Elvis, with “Follow That Dream” and “If I Can Dream”

• Pete Seeger, with “Last Night I Had the Strangest Dream” and the labor song “Joe Hill”: “I dreamed I saw Joe Hill last night, alive as you and me …”

And two TV shows:

• “Dream Along With Me (I’m On My Way to a Star),” the theme song of “Perry Como’s Kraft Music Hall” 

• “Making Our Dreams Come True,” the theme song from “Laverne and Shirley”  

And two very different songs with the same name:

• Aerosmith’s “Dream On”

• The Righteous Brothers’ “Dream On”
