Drug-free flashbacks?

[javagamer]

Hi,
I've been lurking at this site for months (maybe a year), but just got something worth contributing. I've never used an psychoactive substances (except occasionally some non-decaf tea and a *single* glass of wine a night), but I've (with varying degrees of persistence) tried self-hypnosis and lucid dreaming.

Recently, I've had a few experiences of macropsia, or at least I'm pretty sure that's what it is. The two most recent times (yesterday and the day before) I was just at my computer reading stuff when suddenly everything seemed huge. Like, I felt as though I were the size of an ant, so by comparison things like my computer screen appeared as far off mountains. It was a mix of cool because I've been interested in OBE experiences and altered states for a while, but also a little unnerving because it was rather random and I felt very clearly out of it. The most recent time I was able to shift my focus a bit while staying in the state, but moving around a bit stopped it, though I kept a feeling of being not all there. Before both recent times I hadn't had any wine or caffeine.

Now, to the title, I think it could (possibly) be non-drug induced flashbacks. I've come to this possible conclusion because it seems to happen most when I kind of zone-out and shift my focus, which from what I understand is the same thing that can trigger flashbacks. It's also possible that it's sleep-deprivation because I've been up about half an hour late all last week. However, this week I've been getting plenty of sleep, and one of the times it occurred at 4PM.

Now, I'm just curious what everyone else thinks.

P.S. If you need something clarified just ask.
Edit: Made the paragraphs more obvious.

Did it ressemble to mushrooms or LSA/LSD ?
I also had some sort of tryptaminergic flashbacks on cannabis that were more powerful and more pleasant than mushrooms, but it only lasted ten minutes. Ten minutes during which I saw walls moving, lots of colours, loss of vision, and powerful dreemy auditory hallucinations.

I've never used an psychoactive substances

I guess this is answered.

 

[Horrigan]

Right, sorry.

What sort of screen / monitor do you have and whats the screen refresh rate ?


Oh ! And high !

It's an Acer P243WAid (http://www.newegg.com/Product/Product.aspx?Item=N82E16824009125) with a 2ms response time. I think the reason they were both at my computer was just because that's where I spend most of my time, at least where I'm most often not moving.

Also, as restin pointed out I haven't tried any psychoactive substances yet, but I do hope to try LSA soon, so I'll see how it compares. Though like I said it's more of a perception change than a change in what I'm actually seeing.

I asked because the picture on a screen isnt solid , so to say , its being flashed at you just like a stroboscope does . Things that flash can alter the frequency that your brain works at and stroboscopes can cause hallucinations . I`ve read that one shouldnt sit to near to a computer screen and that one should have a light behind it to prevent some problems .

The light flashing bit is wha there are so many car acidents on streets with trees planted along them to .

Ah, like the Dream Machine. I've read about flicker devices a bit, but I assume my computer is far too fast to have any effect. Plus, when I tried the computer version of the Dream Machine (just a full screen thing that flashes at the right rate) I didn't really get much of an effect, but my eyes were closed so I guess I wouldn't have noticed something like macropsia. Plus, when it happens if I shift my focus it does look like it's flashing for a moment.

Exactly .

With those programs one has to be carefull . Most of them dont realy work . I`ve never found one that does . The only thing like that that worked for me was a brain machine = one with a pair of dark glasses that had flashing lights in them and had a pair of ear phones that played clicking noises . When you stoped seeing the lights and the clicking noises sounded like one click the effects were realy relaxing .
