I can't remember ever falling asleep within 15 minutes of laying down, even before I was sick, but I can always hope. So, here's "Gaude, Virgo Mater Christi," ("Rejoice, Virgin Mother of Christ") composed by Hugo Aston ca. 1530.
No pictures to look at, no Bible verses to read. Just 15 minutes of music and a blank screen. Al though it doesn't exactly lull me to sleep (nothing does), it does give me something else to focus on besides a screen and my thoughts long enough for me to feel relaxed, so I thought perhaps it might help you.
Suggested verse to repeat if it's a difficult day (or night) is from Psalm 4:8a
PRC buddies, remember to breathe!
"In peace -------> 5 count inhale
I will lie down and rest," -------> 5 count exhale
Gaude quia tui nati -- Rejoice because of the Son
quem dolebas morte pati -- at whose suffering death thou wast grieved
fulget resurrectio -- the Resurrection now blazeth forth
Gaude Christo ascendente -- Rejoice at Christ’s ascension
et in celum te vidente -- even to heaven, in thy sight
motu fertur proprio -- He is borne by His own motion
Ave plena gratia -- Hail, full of grace
Propter plagas Jesu Christi -- for the sake of Jesus Christ’s wounds
quas cruentas flens vidisti -- which thou didst weep to see bleeding
pro nostra miseria -- for our wretchedness
