Portugal - Weird Rumbling in the sky

According to some like David Wilckock that sound is made by underground bases ventilation system.

Surely you have those in Portugal.

Not saying that Wilckock is necessarily right.

Where my friend? I'm in Lisbon and i didn't notice anything.

I heard a rumbling like that yesterday in the afternoon for about 30 sec. Lisbon, Portugal.

Don't remember the time exactly, but it was night.

Thread: LOW RUMBLE ALERT: Western Washington/ Seattle low wumbling noise right now. (Page 2)

I wrote that in the other thread.

santarem.

funny cause many people listened to it and said it was probably a jet plane. BUT that was a HUGE rumble, not a fucking jet.

Last year we had a similar experience and I posted about it in here, I used the wording "like someone was moving furniture in the sky" cause that was what sounded like, you know? when your upstairs neigbour is moving furniture, that KKKKRRRRRRTUMTUMTUM sound? But multiplied by 1 million times, like someone was opening a crack in the sky (if the sky was made of steal or stone).

Yesterday I heard a rumble in the sky again. About 40 seconds duration, started strong and slowly fizzed until it stopped. Very strange.

Lisbon, Portugal. Near Estádio da Luz.

Oh, and it was about 11:00PM (23h00)
