As a semi-related aside, I have epilepsy and one of the signs I am about to have a seizure is a sense of presence. It's really hard to describe but I get an intense feeling like someone is watching me close by. It's a very familiar feeling, last time I had a seizure, just before I fell to the floor I began to run away from what I perceived as a presence. Not fun.
My “aura” feels like encountering a bad memory. Like an overpowering bad memory tied to a place. I can see how it could be interpreted as a mystical experience
>Jack Hitt, a journalist from Wired magazine, visited Persinger's lab in 1999 and expressed confusion over Persinger's post-stimulation debriefing ("One question: Did the red bulb on the wall grow larger or smaller? There was a red bulb on the wall? I hadn't noticed.") and reported: "Many other questions suggest that there were other experiences I should have had, but to be honest, I didn't. "
What a joke. Why is this in HN? There are better examples of suggestibility out there.
I’ve had good results with a DIY version of a hypnogogic light.
I used one of these at a psychedelic science conference in SF but they wanted $25k to buy it. So I set out to build an open-source version for under $100.
The LSD (Light Stimulation Device) can be built for under $50 and is being used for therapy, relaxation and inducing psychedelic like experiences.
Current version is made with ski googles, lith ion USB rechargable battery, Arduino with Bluetooth and can pair with a terminal program on IPhone.
The whole project is on GitHub and can be found here:
Will do! I would like to add, it would be kind of nice if you added a picture of yours to either your site or the github repo. I can see the premade ones and get an idea of what's going on but it would be nice to see a fully built one.
Someone was going to do a mini-doc about the project and we were going to do a full how to video as part of it but then... COVID killed the video star.
This made me recall some wild online catalog website from the early 2000s that was primarily known (and advertised) for hoverboard sales, where the hoverboard was basically a small noisy gas-powered rectangular hovercraft you could stand on. I think I first saw their ad in Wired, or maybe a gaming magazine. Anyway if you dug into their catalog there was all sorts of wild stuff, from sleep masks that used LEDs to induce lucid dreaming to things more like this. Anyone know the website I'm talking about?
I don't know the website and I can't speak to lucid dreaming, but the most incredible "sacred geometry" effects can come from "brain machine" or "audio visual entrainment" devices. Mitch Altman had a classic Make Magazine build -- the things are essentially LEDs flickering around 10hz alpha. We built one recently with Arduino to support open eye meditation -- and you see some pretty crazy things generated by your visual cortex.
Interestingly, the effect was discovered by the neuroscientist purkinje while at the beach as a boy. He noticed that waving his open fingers over his eyes produced geometric hallucinations and later published his drawings -- back in the mid 1800s.
A web article with an illustration. I can't find it. But from "Purkinje's Vision: Dawn of Neuroscience"
"The first phenomenon described by Purkinje was novel: He produced flicker, while
looking at the bright sky, by waving his fingers in front of one eye and reported seeing
checkerboards, zigzags, spirals, and ray patterns (see Fig. 3.2, Figs. 1–4). They were
called shadow figures by Helmholtz (1867, 2000b) and are now referred to as
stroboscopic patterns (Smythies, 1957), although they were described before the
stroboscope was invented."
Adafruit used to sell the kit (not anymore), but you have the instructions, parts list, pcb files and firmware (on the download section) and everything here:
Do the LEDs “induce” lucid dreaming or are they just a cue for you to look for? Because the cue thing might be slightly less absurd. If you get in the habit of performing “reality checks” (is checking for things that would be present in reality but not in a dream or vice versa), you would notice when you were dreaming and would hence have lucid dreams.
Of course, it’s still a dumb product since you can just check whether written text changes when you’re not looking at it, but it’s not necessarily as dumb as it sounds.
Same, it's pretty difficult to take notes while attempting to rescue someone from a possessed building that looks a bit like a brutalist interpretation of the Globe Theatre, what with having to fight your way through its zombie-like denizens and arguing with a disembodied voice that seems to be controlling the lighting.
I'm not really sure what I'd do differently in a lucid dream anyways, my subconscious seems to have a better imagination than I do. Remembering more details from dreams would be more important for me I guess.
> since you can just check whether written text changes when you’re not looking at it
To throw an anecdote into the bucket, I've had a dream where I read a word, and it didn't seem to change on closer inspection, and I remembered it when I woke up. But it didn't cue any lucid dreaming.
There are a lot of wearables promising to do everything, it wouldn’t surprise me if you were talking about this site. Although it wasn’t around in the early 2000s.
Yes! I remember browsing this site as a child. They had all sorts of whacky stuff for sale, like “anti-gravity” devices. I think I found it through the ads in the back of Popular Science.
On a side note, I remember the first time I tried an isolation tank; how I fell into a deep sleep that was different from all previous ones. Felt like my consciousness was halved but not quite gone (the way it usually is when you fall asleep).
It was very pleasant. Like an idle dream. An hour went by in a few minutes. I’ve tried replicating it a few times but never had the same success as the first time I went.
I’d be curious to know what other states of consciousness exist (and how to consistently trigger them).
I’d pay good money for some experiences I can do in the comfort of my home.
This is one of the things I've always wanted to try. Even if it is hockey pseudoscience as long as it's not actively dangerous it could be interesting.
Alas this and the overview effect are two things I'll probably never experience.
I thought for most my life that the domain of the objective and the domain of the real were equivalent. But I missed the subtle gradation toward uncertainty, maybe seen as concentric concepts starting from center: commonality of perception (objective) -> body’s reaction to reality (subjective) -> reality itself (unknowable totality).
The God Helmet is an objective thing you wear (with magnetic property on/off), with a linguistic component (the story of what it will do), and a subjective component (the unique experiences the person brings to it and from it). If the resulting experience has no measurable/repeatable effects across all people, then it is by definition not admissible as an objective phenomenon (i.e. it does not fit the lowest common denominator of experience).
