2 hours before: Dim the lights and huff some melatonin
2 - 1 hour: Get in bed and read a book. Maybe some more melatonin
Then fall asleep
I don't use my phone or any electronics and try not to talk too much with my roommates during that time. I also found that if I take ritalin or drink coffee less than like 8 hours before sleep, that I have more trouble falling asleep.
Obviously your mileage may (and will) vary
I know plenty of people who adore Disney / Pixar movies, but merch isn't really a thing for them
