Psychomantium Mirrors - Past, Present, Future?

I am using the laptop which has the screen replaced. Unfortunately, the replaced screen is of bad quality and has a very obvious flicker, especially during the night. In my apartment I am using it attached to the monitor so it doesn't bother me, but currently I am away, so I am looking at the laptop screen directly. What I noticed a few days ago is that if I am using the laptop late at night, with a very dim background light, something happens to me. I feel a very familiar feeling to me, it's like something is tickling me in my chest. It's not a physical feeling, but like an emotional feeling. It used to happen to me randomly before, and I don't know what triggers it. But this thing works every time, with the proper dim background lighting, and if I am tired. It doesn't work during the day.

Once, I was reading something interesting on the laptop late at night, so I spent a lot of time looking at the screen with this feeling in my chest. After that, I couldn't sleep normally all night because I was constantly feeling this tickling. But last night I stopped looking at the screen as soon as I felt the feeling. I was able to sleep nicely after that, and I had some interesting emotional dreams. I think that this flickering light has some kind of effect on me, which caries on into my dream state.

I used a Flicker Meter application on my phone and I measured a flicker of about 265 Hz. It goes a little bit up a down, but I don't know if the screen is changing the frequency or the application cannot measure the correct frequency with my phone camera. It's probably later.

I don't know if there is anything special about this frequency, if it really is 265 and not 240 or something else. So far, scientists measured effects of low frequencies below 100, so there are no studies with this high numbers.

But it seems that flickering lights can be powerful tools, if we learn how to use them properly.

I still haven't figured out this flicker. But I found this article, which perhaps goes into the right direction.

Evidence suggests that electroencephalographic (EEG) activity extends far beyond the traditional frequency range. Much of the prior study of >120 Hz EEG is in epileptic brains. In the current work, we measured EEG activity in the range of 200 to 2000 Hz, in the brains of healthy, spontaneously behaving rats. Both arrhythmic (1/f-type) and rhythmic (band) activities were identified and their properties shown to depend on EEG-defined stage of sleep/wakefulness. The inverse power law exponent of 1/f-type noise is shown to decrease from 3.08 in REM and 2.58 in NonREM to a value of 1.99 in the Waking state. Such a trend represents a transition from long- to short-term memory processes when examined in terms of the corresponding Hurst index. In addition, treating the 1/f-type activity as baseline noise reveals the presence of two, newly identified, high frequency EEG bands. The first band (ψ) is centered between 260–280 Hz; the second, and stronger, band is a broad peak in the 400–500 Hz range (termed ω). Both of these peaks display lognormal distributions. The functional significance of these frequency bands is supported by the variation in the strength of the peaks with EEG-defined sleep/wakefulness.

I don't think that this flicker is useful for psychomantium, but perhaps it could be useful for something else.

I keep thinking about candles. It seems that the height and uneven distribution of the candles will affect their flickering. The tallest candle kept flickering. When I compare it with the mini-fireplace, it also did not flash as stably. I apologize if I write here things that others have known for a long time
