There are people to whom sleeping in a completely silent room is equally incomprehensible.

I have pretty hefty hearing damage. Am I supposed to turn everything off and listen to nothing but "EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE" all night?

You can sleep without one?

I grew up around them, so my brain tuned ticking clocks out. Certainly I've lost that ability since then but I haven't encountered a bedroom with a ticking clock in a long time.

I don't know how people sleep with all the blinding blue LEDs so many electronics emit at all times.

My grandparents had a large mechanical clock in their living room, where we would sleep on the floor when visiting as kids. The right "tick" would be nostalgic. I might go look for some ambient noise tracks with clock ticks...

I hate this too but I’ve got to have water dripping to sleep

What do I care how loud it is? I'll be asleep. Things like that only bother me when I'm awake.

I'm trying to think of a time a noise was distrupting my sleep and only example I can think of is waves hitting the boat hull. It's quite irregular sound which is why it bothers me. Music, talking, fan, road noise or such doesn't effect me at all.

It's the rhythmic/repetitive pattern. It's just another form of white noise.

For me it comes down to repetition. Repetitive consistent sounds I can ignore. Random sounds though keep me up.

I'm so ADD that I intently listen until I forget and get distracted by some other thought. I also can fall asleep fast after hitting the pillow so there isn't much time to linger on it.

I'm used to it. It reminds me of being at my grandmother's house.

Mine even rang it's bells at every half-hour and hour. So 12 loud bell rings at midnight. In my bedroom. I slept well.

Honestly I think it's because I get used to the sound. If the ticking and ringing are always there, the brain just ignores them, even in sleep. For subjectively nice sounds (like those of a nice pendulum clock) at least.

I don't have it running anymore, the weights would eventually hit the piano.

My husband snores so I can help here, eventually you will tune anything out, with enough exhaustion.
