I keep hearing a tune upstairs but can't find it

[Motherofmonsters]

I think I'm going crazy, I keep hearing a tune playing upstairs and I have no idea where it's coming from.

It started a week ago and it was very faint and I have only heard it when I'm alone. DH hasn't heard it.

He's out again tonight and I can hear it much louder but I still can't find it. It's not like a song more just a couple notes of a childrens toy repeated.

I have children so not unlikely but I don't know where it's coming from. When I go in every room it quietens

I think I'm going insane. Surely it would have run out of batteries by now

What do you mean "When I go in every room it quietens"??

Progressively? Or..you feel like you're getting further away from it?

Do you have a neighbour? Its possibly coming from their house and you're hearing it through the wall.

Have you got toys in a big toy box? I had a musical toy in a big ottoman that kept going off for a couple of seconds as another toy was pushing on it.

Airing cupboard?

Put any toys in the loft recently??

Could it be a neighbour's doorbell? We had similar a few years ago when the neighbours got a new bell, we had to alter ours to a different frequency or something, because every time someone rang their bell it was our bell that picked it up.

I had this the other day. It drove me nuts. Everytime I left the kitchen it got quieter and then in the kitchen it got louder.
Turns out my google play thing had been on and just turned down low. Drove me nuts for hours

It feels like I'm getting Futher away from it. It's still going off now.

I'm detached so no neighbors close enough. There are a lot of toys in the attic so could be something up there. Were getting the Christmas decorations later so I can investigate further

If noone else hears it, it could be auditory hallucinations

This happened to me earlier this week and no word of a lie I burst into tears when I found the culprit. Genuinely thought I had been losing the plot!
I'd thought it was the neighbours Christmas lights but couldn't hear it outside. Thought something was playing in the background on my iPad. No one else in the house could hear it. It would pause sometimes but otherwise playing on loop.
In desperation I opened the loft hatch and waited, it was up there a fisher price little people Ariel's underwater palace with calypso sounds. It has been there in a plastic box with a lid for at least two years. To make the sound go off you need to lift the lid of the treasure box so I have no idea what changed or how it was going off (I'm too old for ghost stories but eeeek).
Switched off and brought it down. I could still hear it when the house was quiet for about a day after - literally ringing in my ears!
Try the loft, you're probably not going mad!

Oh and I was googling "musical hallucinations" and imagining all sorts of horrific hypochondria!

It could be auditory hallucinations. Have you been particularly stressed or tired lately? I had this happen to me (lived alone at the time, no dc). I was really stressed and over worked at the time. I had about a week of hearing faint like old time carnival music (like the kind on one of those old organ carousels- really bizarre and unnerving). It’s just a weird stress reaction. It’s not a mental health thing, in the sense of experiencing other hallucinations or hearing voices. It’s just something the brain does when under stress. It eventually stopped after about a week and I’ve never experienced it again. That was probably 10 years ago now.

I've had auditory hallucinations before when I was extremely unwell and one of my symptoms was searching the house trying to find where the music was coming from.

Have a look in cupboards wardrobes under beds etc.
Not the same as your problem but a few years ago my dad and step mum had a beeping which they couldn’t find where it was coming from. They both had dementia and would put things in odd places. I hadn’t heard it when I’d been but my stepbrother called and said he could hear it but it seemed to move. It could be heard in the living room kitchen and dining room and hallway. I suggested the smoke alarm but it wasn’t that. He thought it was in the ceiling or a wall I told him to turn the mains electricity off to see if it stopped, it didn’t so that meant it was a battery. He couldn’t find it. The carer found it the following day, it was an old smoke alarm, shoved in a cupboard in the hallway that he supposedly checked, the battery was failing.

Found it! It was a kids walker we put in the attic about 2 years ago

Wahaay! Glad you found it! We had a kids toy that would be set offby the slightest movement - in a creaky wooden house thatcwould be someone going out of the door several rooms away.

Some acqaintanced had something similar and got so fed up off it going off constantly they binned the toy. Next day, binmen been, THEY COULD STILL HEAR IT. Went on for days. They finally worked out that the starlings that lived on the roof had learned the tune and were singing it outside the window!!!!

I had this. Culprit was a portable bluetooth speaker I had left switched on.
