I have a mystery suction cup noise in my house, I can't figure out what it is. Guesses are welcome......

OP, have you considered that the sound may be originating inside your own cranium? There are parasitic worms, for instance.

:cruise big:

sometimes strobing lights replace bells and alarms.

So far, I am going to do 2 things, one is hang out in the attic and listen and unplug the cat heating pad.

I can do these two things.

No

GOT IT !

New roof leaking into the side walls, a DROP at a time. Hollow sound, as result of INSIDE the Walls.

Hope not; expensive to repair !

Excellent call. That's the sound.

Explodng head syndrome

Shit, that might be it. I had a leak by the chimney.

A drop wouldn't sound like suction would it? I am under warranty.

It is more common over the age of fifty, although it has been reported as young as age 10. Attacks can be one-time events, or can recur with attacks increasing or decreasing over time, sometimes with no incidents over long periods of time.[5] Though painless and not considered to be dangerous, exploding head syndrome is known to terrify the people experiencing it and sometimes can be very distressing. Sufferers often feel a sense of fear and anxiety after an attack, accompanied by an increased heart rate.[6]

The mechanism is also not known, though possibilities have been suggested; one is that it may be the result of a sudden movement of a middle ear component or of the eustachian tube, another is that it may be the result of a form of minor seizure in the temporal lobe where the nerve cells for hearing are located.[5] Electroencephalograms (EEG) recorded during actual attacks show unusual activity only in some sufferers, and have ruled out epileptic seizures as a cause.[3]

Related phenomena[edit]

These loud noises are a common feature of out-of-body experiences. In surveys, as many as 85% of respondents indicate perception of them during the onset of such experiences.[7][8]

Yeah, it's just that lil' pixie running round making noises, fawking with ya.

That lil' fawk must have 3 dozen of my socks by now and god knows what else.

You're being sucked into another dimension for questioning.

I am glad I didn't just let it go if this is it. thanks

Where's my Prize ?

Gophers.

When you hear the sound, do you experience a rapid heart rate? A sense of terror or horror?

Well, not really but now that I think the roofers messed up maybe so.

Plumbing drain pipe issue.

I got my super duper new flashlight out and looked at the roof over the area in question and everything looks fine. Yay!

The same aliens that took Steve Martin's character in Roxanne?

do you have baseboard heating?

nice

Human fly?

No. it's all in the up high.

Once the workers got a soda can down the sewer vent and then closed it in. We could here it when the wind blew hard. We never knew what it was util we had to redo plumbing.

I think that's kind of funny.

Your house is obviously haunted. Get rid of those bodies you hid in the walls.
