Funny you should say that. Tin hat merchants will tell you all about man made tunnel / cave systems that are being constructed by 'them', because the saucer lizards have told 'them' to get ready for what's coming, but utmost secrecy has to be maintained, lest the proles get wind of it and start revolting. It seems 'they'need to work out a way to do it more quietly.
It's that low pitch distance humming noise which science can't find an answer for, usually described as a diesel engine idling.
I tend to hear it in the evenings, autumn to winter time but only indoors, step outside, go in the shed or the garage and I can't hear it.
My better half and the neighbours can't hear it and just think I'm potty, but it is widely reported.
Some say it's distance factories, generators, waves all sorts of reasons. I live in a rural area and just can't track it down.
Somebody prove I'm sane by admitting they hear it too please !!

Only 20yrs old, that's nearly new. Maz and I were talking about the fridge freezer here and she knows she had bought it before she moved to this house.It's twenty years old and on its last legs. It doesn't have a radio, make ice cubes, give you a back massage, or offer investment tips.
However, it does get yellow beer cold in short order.
