Eldritch lucid dreams get fun when you're the eldritch one. Oddly enough, I've had dreams where I have hung out with other eldritch horrors as if they were equals, and spent most the time getting stoned and drunk with them. It's weird seeing such a being of utter horror hit one up, and even start acting like a stoner. It's unusually hilarious, because you'd never expect such monstrosities being so chilled out, and being... normal.
It gets weirder when you can actually understand the eldritch tongue, and can speak their language as well in these dreams as well. Turns out, many of these gods are getting sick and tired of how sacrifices are being handed to them. I mean, they want someone to hang out with; not a bloody mess that's not much for conversation. They want to be understood, not feared. Looking uglier than sin kinda doesn't award them many points, not to mention speaking a broken inverse-starfish-Latin of sorts is a tad difficult to understand or translate; so basically, they have to accept that humans are just too closed-minded to interact with. I mean, with how history goes, we've been homogenizing ourselves into a single class/race of species. We might not be a friendly race to interact with be you eldritch, etherial, or just a plain 'ol off-worlder. To greet us with their heaviest hitting weapons out (like quantum nukes that can wipe out star systems) is probably a suitable "Hello" for any race that has studied us sufficiently. From what I've heard from these things before, Humans are none more than a very stubborn virus with sentience that's harder to remove from existence than previously thought. We escape our prison of a planet, the rest of the universe is royally fucked, and no god can stop us once we travel out of our world. The last god that tried to settle us got brutally killed by us; and he was probably the most chill of them. The fact we were willing to wipe out their most peaceful advocate/ambassador without a heartbeat to wait, because of our own power-hungry "needs"; I think being armed at all times is plenty normal to behave around us.
I wouldn't put it past any non-human being to mistake us as demons that escaped from Hell. And the worst of them all. In fact, I think in my dreams interacting with said gods, they were initially scared of me, but opened up when they learned I had no intent to harm; although they needed to scope me out thoroughly at a supernatural level to be sure. And I was the paranoid one. Nothing more paranoid than a species of higher beings that are aware that there are things scarier than them, and they can be lesser species in massive numbers; so yes, I guess a virus or swarm of locusts is a good way to describe us Humans. Theoretically speaking, look at Mars and Venus, and assume Earth is another shot at living for our species, and those last two were failures of our existence; or we took everything we could from those worlds.
EDIT:
On another note; I also had a dream where The Devil asked me for the blood of my first born, in a dream that I had a family of my own. They were not amused with my blood sacrifice. I mean, how would you feel if you were mailed a bloody band-aid ball? Yes, I owned the Devil on a technicality. My kid was apparently accident-prone, and I was well-stocked with medical supplies. Hearing even the Devil call me a "sick bastard" is strangely satisfying and amusing. Never bothered to ask for a sacrifice from me again. I think I broke him.
Strangely enough, I think I have more of a vitrolic smartass friendship with the Devil in most of my dreams, rather than him always being the enemy. He does do the usual Devil thing, and smirks and maybe flips me off at my answers to his usual tricks. In a sense, I think he enjoys the fact that I can play on equal ground against him. Instead of casting him back to Hell all the time like most others would, or fearing him even; I show him the light instead, by being a total loon with his challenges. In a sense, I burn him back with his own tricks, in my own style.
