Opinions are like a-holes, everyone’s got one
I'm going to show you mine, don't call the police.
I have some bad news, likely it won't be as simple as waving a wand and shouting "
avada kedavra!" That's a fairytale depiction of magic. In reality, you'll either have to take some kind of psychedelic or evolve yourself over a long period of disciplined time to develop magical perceptive faculties.
I can't speak to the reality of reptilians, but I can say confidently that this material space isn't all that's around us, and it just kinda makes basic logical sense to me that there would be beings living in these "extradimensional spaces", made of shit we can't register with our 6 senses. These beings don't even have to be alien to Earth, they simply live on an Earth we can't perceive, in realities so alien to ours that there aren't even celestial bodies anymore. Still, that doesn't make us helpless to comprehending activity coming from this "higher space" interacting with ours, it's just jarring because to us it makes no logical sense, and that jarring-feeling is what we have to hone rather than be overwhelmed by or fear. I need to be clear that we aren't reinforcing prejudice or bigotry here, we're developing our ability to detect things that aren't "natural" to our reality, but just mimicking it. We have to work with what we have first, ground ourselves, build ourselves, then we could properly develop extra-sensory perception.
Frankly people can be more strange and detached from reality than any imagined alien, and working with these people will help us ground ourselves. Whether Reptilians are real or not, there is a truth that they represent symbolically within our society, and that is psychopathy / Sociopathy. People walk around, mimicking our behavior, cruel and pitiless, and because of this extra edge they can be very successful in our society. Not all of them are bad, they're people too, but when they go rotten they hit extremes we can struggle to imagine. With companies slashing at each other like mega-conglomerate beasts in a corporate jungle, it wouldn't be hard to believe that people without feeling, empathy, people who thrive off high-stress situations and can mask themselves perfectly would be the ones at the wheel of societal decision-making. Scales or flesh, it doesn't matter the reality is undeniably the same.
How do you detect a Psychopath? You won't see lizard eyes, but you'll see a lack of emotional affect. Real magical sight isn't out of a comicbook it's through gnosis: potent objective empathetic awareness, free of opinion, only truth. The reason we hardly recognize the Psychopath sitting across from us is because A: we aren't looking for that and B: we are living in our own heads and project our own ideas of people onto the beings they actually are.
There's books written by people who have made careers studying people without emotion, and servicemen who've spent their lives dealing with these people in the streets that have shared their experiences in illuminating interviews. Studying
actual people isn't just more useful to your day-to-day life than reading up on Bloodlines, but it's the foundational first step to developing your awareness of what's happening around you. Insider put on youtube a great interview with an actual Sociopath with a PhD in Psychology called "How Sociopaths Actually Work" and it's... revealing. She talks about how she needed to commit small crimes regularly to avoid having her pressure build up to the point where she'd need to do something violent. There's also plenty of interrogation videos and true-crime videos with footage of people that lack all the qualities we use to describe as human.
The point I'm trying to get at is this: If you want to detect beings who do not come from our level of reality, you first need to be a master at detecting divergent beings that
are. It's a skill you continually build on until it's second nature, you already have it to an unconscious degree, you've felt it anytime you've intuitively detected something within the "Uncanny Valley" or those feelings of existential dread you got the first time you saw the movie "The Thing".
It would be nice if you could use a spell to see extra-dimensional entities or aliens, but honestly you'll just have to develop this clairvoyance consciously, and that's hard work.
