Sleeping rituals?

Perhaps ritual is not the right word to use. But I’ve found that I never go right to sleep, I usually have to play music at a specific volume—not too high that it keeps me awake, but not too low that i cant hear it—or watch a movie right before I go to sleep. If i think of any idea’s i have to write it down or I fear I’d forget them.

So I’m wondering, is this normal? Do you have specific things you have to do before you go to sleep? Or do you crash as soon as your head hits the pillow?
