STRANGE SOUND IN THE AIR AT NIGHT [1]

Namasté!

My dear Lightworker family, today I have a question to all. ;)

Last night, from the 25th to the 26th of November I woke up at 02.00 am GMT because a strange sound didn´t let me sleep. It was a kind of metallic sound and the closer it came, the more changed it into a kind of "motorbike - sound" on a high level.

First I thought that maybe this sound came from the traffic, but at this time usually here it´s very quiet.

Then the sound swelled up, down, up, down, up for the next two hours.

There was no way to fall asleep because it was really loud and all my chakras reacted like crazy. It wasn´t a bad feeling at all but weird, hard to explain.

On Wednesday, at exactly the same time (02.00 am GMT) the same happened and it also lasted around 2 hours.

Did anyone of you experience a similar thing around this time?

It wasn´t at all the first time that I heared this sound. Last year it happened several times but I never got an explanation about it.

Can anyone help me with this question?

Thanks a lot in advance. :)
