Untill I came across the Dyson Delima I was sure we had communicated with aliens.

What about the Dyson Dilemma made you doubt such? I'm not sure I understand.

The image you posted is a pretty compelling one in my opinion! Though there's artwork from all around the world from pretty much all cultures, so to me it seems pretty overwhelming.. Almost all ancient cultures reported interactions with beings from the sky and quite a few even directly credit them with building their megalithic buildings.

It is interesting that you mention how it's common to hallucinate and that we do it every night when we dream and I think there may be a connection there, some researchers believe that aliens are less physical and more from another dimension and that would make a decent amount of sense, though I think there's physical ones as well and when I say "mass hallucination" it's like, multiple people seeing beings at the same time, like a "shared experience" and such similar reports separated by so many years and geographical distance.. Just seems like it's more than just something in peoples heads.

Perhaps @leaky20 was correct and consciousness is some underlying force of the universe. The acts of altering our consciousness either through sleep, meditation, or drug use help us break away from that objective experience. To one where the normal laws bend at the more ironclad law of consciousness. In such a universe where consciousness was the primary building material of everything, telepathy, perhaps even faster then light seems like a rational possibility.

That's an interesting possibility I've been considering more and more especially recently after watching videos on YouTube about the Holographic Universe theory and "shadow people" which I had an experience with when younger.. Perhaps there is some kind of.. Mental thing going on where we have access inside our own minds to not only things a long distance away, but.. "everything".. And some of these experiences may be sort of a "bleedover" or a "glitch" or something like that.. Hmm..

Those beings we have been communicating with could be many galaxies away so we would never see their mega structures. Or perhaps even other demensions.

Yeah I'm open minded to that. Fascinating to think about, however in the end I still tend to believe we have real physical beings visiting us.. I've heard so many testimonial experiences from people who go into great detail which seem like more than just dreams or hallucination. Yet in the end I admit I don't know..
