There is something wonderfully predictable about falling asleep to the same show for the 500th time.
You already know what happens. You know the characters, the voices, the rhythm of the dialogue. You might not even be properly listening anymore. The story has become familiar enough that it no longer asks anything of you.
And yet, this kind of thing is often described as a dependency.
But what if it isn’t dependency? What if it’s regulation?
Familiar sensory input can give the nervous system something predictable to settle around. When your internal world is busy, silence isn’t always calming or restful. Sometimes silence leaves more room for thoughts, sensations, worries, memories or the awareness of every little sound in the room.

A familiar show doesn’t require much from you. You already know what happens, so there is nothing to work out, anticipate or pay attention to. The voices, rhythm and background noise simply become something known.
It can provide just enough input to quieten some of the internal noise without demanding attention.
For some neurodivergent people, that familiarity can help create the conditions where sleep can begin. Just as someone might find comfort in a particular blanket, sound, position or smell, a familiar show can become part of their way of settling.
Sleep itself is involuntary. We can’t command someone or ourselves to fall asleep, but we can sometimes understand and support the things that help their nervous system feel ready to let go.
So rather than asking, “How do we stop them needing this?”, perhaps we can ask, “What is this doing for them?” Because sometimes the goal isn’t to remove the thing that helps someone regulate.
Sometimes the thing that looks like a sleep dependency is actually the thing helping sleep happen.
