When people use the term 'greys', are these beings that live in another dimension? Or just aliens in general?
You have to understand that they are as biological as anybody else. However they are very much using Astral Projection to operate on the astral level.
And I already explained that many of them have already died so they are bound to operate from the astral level.
worries me why these things are flying so low and so slow.. are they looking for people?
The triangles are not planes. They are presumably hover craft and they possess flight capabilities that are physically impossible for airplanes.
When they are looking for people, they are looking for people with special genetics that they mark and separate like wheat from chaff to be part of special corporate programmes.
Many psychics involuntarily work for them. Memory is usually erased after the sessions.
I've heard stories about alien abduction, where people were brought to different dimensions for years at a time, but when they returned it had only been 3 minutes? And, conveniently, nobody had been with them at the time..
This is because most abductions are astral abductions where the astral body is extruded from the victim and taken to an astral locale.
Time in the astral world is not sync with the physical.
I personally don't believe most stories like these
But then I'm sure you would believe hundreds of thousands of testimonies before court to serial murder cases that all happened in the same way?
Hundreds of years ago the people ridiculed all those claiming the Earth is actually round and that they have travelled across the globe without falling off an edge

.
Likewise the people of today are treating hollow earth researchers like that.
Ignorance has always been dramatically slowing down the process.
My god people, free your minds!
