As previously stated im just about cured, todays not been a great day ( bit of paranoia, very mild ) but its been a great week with vast improvement however, there is one symptom thats popped up or iv just noticed. It happened pre- hppd but its worse. when reading text sorta floats around. Is this a common symptom and is there any way to try and deal with this, usually i wouldnt bother a fuck, but thanks to hppd unique way of altering thought process, im worried it will spread out into every day life leaving me in some acid like state. Id be very upset at that because i reckon im like 90% healed

At work, the day after the last time I consumed alcohol I first noticed this. Was really stressed out about it till David responded to a thread I made.

For my personally it was a symptom that would come back later and later over the course of a day and eventually just went away. One of

the few symptoms that has gone so far.

try to cover one eye and read if it is gone its quite normal, the most people could see it if they want if i remember right.

i think HPPD and the attention to your eyesight plays a role with this movement thing:

I had that for a LONG time. That was like one of the first symptoms I got.......but after a while it went away completely and I never get it these days. So since you don't have HPPD that bad and you're almost recovered I think it'll prolly clear up for you and shouldn't take too long.

"movement of print or stationary objects" --- this is a 'classic' description of the breakdown of one of the brains two main visual system (but not left and right hemispheres). When you have a little time, look up "ambient visual processing" and "focal visual processing".

In summary, 'focal vision' is where you think. 'Ambient vision' is how you feel and where you are in relation to things around you. The ambient system is high speed, 'primitive' and feed-forwards to focal processing to provide a foundation. The peripheral visual field is mainly ambient. The fovea (center of macula) is usually focal.

Here are some links that you may enjoy. Although they speak mainly in context of TBI, the inner workings of the systems is what is relevant in this context.

While it takes a little time to get a sense of what is going on, it is worth the effort to get familiar with it. In essence with the breakdown of ambient processing, instead of the bulk of visual processing being automatic, the part where you think has to do a lot more and is literally overloaded with information. Thus it takes longer to parse what you are looking at. And things get dropped.

Note: “…individuals lose this ambient visual process and instead are left with a focal processing system that breaks up the visual world into isolated parts. This causes individuals extreme difficulty, not only with balance and movement, but also affects the person in other ways such as in the person's tendency to compress and limit their spatial world. This creates experiences such as an inability to find an object on a shelf in a store. The compression of space causes a focalization process to function both centrally as well as peripherally. This has greater meaning when one thinks of what the experience must be like when all the bottles, cans, and boxes on the shelf is suddenly experienced as massive amounts of detail causing the person to be unable to isolate one detail from another.

Problems listed from the ambient system not doing its job include: “difficulties with balance, spatial orientation, coordination, cognitive function, and speech, double vision, movement of print or stationary objects such as walls and floor, eye strain, visual fatigue, headaches, disorientation, memory problems, cognitive dysfunction, loss of executive function (including reading), an inability to follow sequential instructions, fatigue, irritability, and sensitivity to light

Thanks man il check thos out. Its never reasuring when the word breakdown is used. U seen my latest thread and symptom. Its kinda frightening me

Sorry, not meaning to scare with the word "breakdown" ... how about "when its having a bad hair day" ... "tired" ... "not coordinating"? :o

Actually, optical illusions take advantage of overloading or confusing visual processing. It seems that lots of HPPDers report 'movement' problems, but here is a simple illusion:

There are a number of these on this and other forums. They work by using inconsistant shading so the brain can't really lock onto a correct perspective because there isn't one. So it shifts (vision is highly dependant on contrast).

Aah right I get u thats more reasuring. I reckon the visual snow wore my brain out a vit so these texts wobbles came but now the snows better hopefully its resting and this will improve. As for the morbid semi hallucinations while awake... Theyr kinda worrying

this sounds like that inmy opinion:

the fourth image cant hotlink it sry

i think the movement of letter or carpet pattern wont cause balance problems. its more like the scene in "Fear loathing in Las Vegas" when the two are checkin in at the hotel

This is mentioned in every drug forum of the world and seems to be one of the most "visual disturbances" after psychodelic consumption. the most people having it never heard about HPPD like me 6 years ago.
