Anybody need a nap?

Both the change of seasons and the recent start of daylight saving time always seem to throw me off schedule.

So, how about some songs about sleep — and, for equal time, sleeplessness — to set the mood?

Let’s start with everyone’s nighttime friend, “Mr. Sandman,” courtesy of the Chordettes …

… And then visit three of our most famous fictional sleepers:

• Sleeping Beauty —and one of her big moments “Once Upon A Dream.”

• Washington Irving’s Rip Van Winkle, remembered in this doo-wop song by the Devotions.

• And Sleepy, one of Snow White’s seven diminutive friends.

Then on to some more music:

Sleep songs
• We’ll start with the Majors’ “A Wonderful Dream,” to fulfill the headline’s promise of a list starting with an “A” (but there’s a whole lot more “Dream” songs in this list here).

• “Sleep,” Little Willy John’s ode to bedtime.

• Santo and Johnny’s No. 1 instrumental, “Sleep Walk,” and the Supremes’ vocal version.

• And another popular instrumental, “Sleepy Lagoon,” by Harry James and His Orchestra, and Dinah Shore’s vocal version.

• “Petula Clark’s advice, “Don’t Sleep in the Subway.”

• And two very different songs that share the same title, “Talking in Your Sleep” — Crystal Gayle’s take on the subject and one by the Romantics.

• And two similar laments: Linda Scott’s  “Who’s Been Sleeping in My Bed?” and “Somebody’s Been Sleeping in My Bed,” by 100 Proof Aged in Soul.

• ZZ  Top’s hardly soothing “Sleeping Bag.”

• And the downer in the bunch, “Endless Sleep,” Jody Reynolds’ melancholic story with a happy ending.

Sleepless songs
• “Two Sleepy People,” by Bob Hope and Shirley Ross, from the 1938 film “Thanks for the Memory.”

• Bobby Edwards’ “You’re the Reason” explains why he’s not settling well.

• Frank Sinatra, too, blames relationship problems for his sleep problem in “Learning the Blues.”

• As does “Walking the Floor Over You,” with a superstar country lineup of Ernest Tubb, Merle Haggard and Chet Atkins.

Waking songs
Five “waking” songs should leave us refreshed for a new day:

• “Wake Me Up Before You Go-Go” — can’t leave out this Wham! hit, I guess.

• Actually, sleep proves to be a problem for the Everly Brothers in “Wake Up Little Susie.”

• “Wake Up Everybody,”  a call to action by Harold Melvin and the Blue Notes.

• Paul Williams’ sad “Waking Up Alone.”

• And we’ll end on a happy note with “Wake the Town and Tell the People,” by Les Baxter and Orchestra with the Notables.
