This thought has occurred to me.

I've witnessed advanced channellers of 'Daemons'; not demons but simply spiritual entities/spiritual energies (I'm not exactly sure what/how to describe them). Some high ranking, some not so much, but frightening none the less.

They're vital in research as most of the time, a lot of historical evidence and old books I've read, it gives clues or pieces to a very large puzzle.. and sometimes these beings assist in hidden knowledge.

With that said, I take what notes these people give me with a grain of salt but over all, I often find that these individuals are often 'manipulated' by their daemons.

Oddities, coincidences, and encounters, often plague these people after they do such taboo acts; often times by said 'medium' you bring up...

Sure, I get that ETs from outer space 'could' exists... but what is much more fascinating are these 'timeless/eternal' energy beings.

I also lean to what you are saying: mediums often spread word on the behalf of said spirit/daemon.
