While LSD is intense, saying it's a portal to demons is religious nonsense, and of course that guy Owen, who ironically enough made the cover art for Bronze Age Mindset, has an entite page dedicated to Christianity
I'd write his experience off as having a bad trip.
Lots of people on X/Twitter like to sensationalize different concepts like demons and things being demonic. While some people might genuinely feel that certain experienced/drugs are demonic, it seems easy to just make stuff up and exaggerate for engagement. Make something sound more sinister and bigger than it actually is.
Now if we're talking about facing our own demons, anxiety, fears, and of course our gut health, that's much more valid. People undermine the importance of gut health with things such as psilocybin mushrooms or LSD, especially LSD as its a much longer and more intense experience. LSD makes you understand the importance of your environment, your energy, other people's energy, etc. It can put your problems and what you've been neglecting doing in your life to the forefront. I'd say the normie LSD formula is think about bad thing, let that bad thing effect your mood, freak out about said thing, and have a bad trip. Of course there's bigger problems, lots of fear inducing propaganda, and general uncertainty in this world, but as long as you understand you must keep going and have a positive friend who knows how to keep you in a positive mood and mindset, you can put yourself back in the positive happy trip spot.
A big thing for me was seeing how beautiful nature was and how dysfunctional a lot of humans are and human creations, LSD activates synaesthesia where you can feel what you see, and vice versa. I'd research more into synaesthesia honestly. Again, it all goes back to your environment, your mindset, way of thinking, your trauma, etc.
