Top 10 Sounds that are Considered Normal in the Daytime but are Horrifying at Midnight

You know what's more scary than most horror movies? A sound of a child's toy triggering itself at midnight. Bonus points if the battery is low and disrupts the sound.
Quite terrifying, and the image does nothing to help with the fear.
I lived for a while in a home that had a cat which constantly tricked me into thinking my housemate was home even though he wasn't.
You can consider this as a good reason not to own cats.

Exchanging conversations via phone calls is perfectly normal. But you know what's unsettling? Getting a phone call from a loved one around midnight. Happened to me when one of my relatives had a stroke, crap pretty hit me hard on that one but fortunately he had a good recovery.
Bonus points when you hear somebody whom you don't know shouts your name. Could it be paranormal activity, or some obsessed stalker? Who knows?
Even scarier when it's your bedroom door.

Now this is something most people would find annoying occasionally, but have you received a weather alert buzzing at 3 AM? That hits different.

This would 100% scare me if it was at around 2:00am! As someone who believes in ghosts, this would creep me out big time, and personally I think children ghosts are one of the scariest ones there are!
Children playing outside? How delightful. Children playing outside at 3 AM? Now that's a horror movie.
Anyone else get jumpscared over a sudden creaking door, only to find out it was just the wind? Happens when I forget to close the windows.
Somewhere lies a kid who took "knock knock ginger" too far and proceeded to ring one of the doorbells at the house next door at 3 AM.
We don't hear this much at daytime, but it could be concerning.
This is so creepy.
By no means it's not normal in the day, but it is horrifying in a quiet night; indicates that something may have gone tragically wrong in that house next door.
You know those pleasant nursery rhymes those trucks play in their music box? Now picture as if that truck was casually drifting by the road at 3 AM with the same melody.
If some sketchy dude came up to my house with an ice cream truck, What the heck are you trying to do? It really gets more creepy the more you think of it.
In multiple cultures you are NEVER supposed to whistle at night. If you heard someone whistle back, it means you've awoken something that you shouldn't have.
In eastern cultures it is known that whistling at night can summon ghosts into your home. Never do this.
More of a personal thing, but this tends to be annoying at the day, but at 1 AM when you're just about to fall asleep, that's a different story.
Very similar to an object falling to the floor, just as worse.
Not as worse as a falling object from a cat. Maybe if it was a cat you don't own that's an exception.
Especially when it's quiet, and the sound comes off as explosive.
I'm not sure about this, but if the faucet is running with full force without human interaction then surely you've got a ghost in your house.
Okay, clock tower striking at 5:00 PM? Normal. Okay. Good to know. Clock tower striking at 2:00 AM? I'd be scared.
That happened to me one night. I was sleeping by myself was half awake when I heard someone breathing next to me like if they were sleeping next to me, sounded like a little girl snoring, that scared the hell out of me.
Depends on where you live but if its in a suburban or rural area you may get this often
This terrifies me. It's like my house is getting robed or something.
