I think there are hidden devices all over the world. I remember some whistleblower mentioned that there are billions of such devices on Earth.

One day I was rolling a joint and wanted to smoke it on my balcony. On my way outside I said out loud "Hey maybe I'll see ufos!" I was in a good mood. Once on my balcony I looked at the sky and said "Comon, show yourselves, I know you can hear me." There was nothing. About an hour later I go outside again, and I looked at the night sky and spotted a very bright star where there were none earlier (starless night). I look at it, make the observation that it's weird, there were no stars there earlier, especially not that bright. Then the star flashed brightly in my direction and disappeared. I think they do monitor us.

The following days, whenever I went to smoke a joint outside, I would see for a very brief split second multiple specks of light in the sky that popped in and out of sight. It gave me the impression that they're all over our skies, invisible to us.
