Can confirm, though that projection of fear is a real common things like them do, if you do any APing you'll run into all sorts of things that do it, though theirs is ngl quite a bit extra and matched with their unique appearance, wild auras and brightness there's no room for imitation. Anyway, figuring out that fear thing it's an illusion its easier not to be rocked with it. They also project love, mercy etc. They have all sorts of emotions, human like and very very different, hard to tell if those are projections as well or some mirroring done to understand us better. If you do extensive AP they and machine elves are super easy to spot in places way beyond that net, usually encounter them guarding shit and learned to not fuck with what they are nor them since if you see them guarding since it's like messing with the guards of the emotional equivalent of a nuclear wastes pit most of the time.
They also don't really seem to talk much, they prefer to do images, basically the guy talking in memes meme, though one tried to speak to me in Aramaic and I don't know that , and they didn't care I didn't know it was some deep symbolic thing. Glossolalia is another thing they do, especially when singing.
I doubt they are 'angels' they're some strange Jungian collective unconscious psychological benevolence thing at standard or some sort of other dimensional being to be fun. For the later they'd be like corvid researchers and we'd be the crows, that 'demon' thing they do is one of the masks they put on to study us more. They do share a lot of 'comradish' stuff and good will, but the former makes me think more of middle age peasants rebels/nonsci comrades ala Thomas Muentzer, its just simply too ideal but they appear to be beautiful creatures of the ideal that like to help us mostly (or believe they are helping us ultimately, they are very alien and we are nothing alike), so that checks out.
Your experiences check out almost 1:1 with my own when I was doing DMT and other substances. I think most of what you're interacting with have been the back-end angels who mostly stumble upon or are stumbled upon by humans.
I've found them to be a little less incomprehensible if you meet some more human-facing ones. Although, since they mostly communicate with emotions/meanings, we could also be talking about two different entities that both translated as "angels." I've mostly spent my time concentrated on spirits within earth and have only taken minor forays into the Astral. Even then, it's been under watch and protection.
Sounds good to me, I figure I usually meet the weird background ones because I'm poking around AP where I probably shouldn't, or so some have told me. Can't explore RL too much, too broke, can explore weird stuff a whole ton since that's free. I'm too broke for drugs, I do meditation that has similar effects though and probably had 1 too many traumatic events to counter that.
The main 3 I've encountered are hyperspace gemstone wheels with eyes (they move weird, makes me think of Sagan's hypercube), 'holy creatures', these weird 4 parted things folded like paper fortune tellers that also have super fast hyperspace movement part minotaur, big cat, bird of prey with an incredibly bright nuclear-blast glow aura, they love to stare deep into your soul-mind, or give that sense, and speak in incomprehensible languages and if you do comprehend them its cause they had it with you and want to be clear, and snakes with like 6 wings that warp space around them so they're usually a ball telling me to 
. Snakes and wheels are cool, the 'holy creatures' are on business and have 0 chill, I get the sense they very rarely interact with people, they're also rare to encounter.
