"seeing little people" is such a hyper specific visual effect, it begs questions. Since I am well aware how my mind fills in gaps in the visual field with attempts to map what I would expect or want to see (try holding your head rigidly ahead and look with a steady gaze at a near field pattern like floor tiles to experience your brain filling in the missing pieces in the field) I ask: what could this actually be? For…

Similar phenomena consistently reported in high doses of Benadryl: little spiders.

Huh weird. When I have a high fever, usually from the flu, sometimes I start to hallucinate. The typical hallucination is lots of "little people", usually doing something I don't like. I wonder if it triggers a similar part of the brain?

I don't get that I just end up with random 1 minute long looping nightmares

Yep, there might be two factors here. From what you describe in your experiences, these seem like real artifacts that occur due to physical changes happening on and around the eyeball? (Photopsia seems to be what you describe).

In my experience when hallucinating (from sleep deprivation), it is the brain failing to correctly interpret patterns seen through the eyes.

For e.g., I would think I see a cardboard box on the ground ahead of me, but then when I get closer I realise it is just dirt of different shades that was perceived as a 3d box. Similar experience when hallucinating people. In my mind I imagine my friend with a certain colour shirt, then during a period of sleep deprivation, I think I see him on the trail ahead of me. But it was just a rock that was a similar colour.

Do hallucinogenics typically affect the brain and also the actual optics? Maybe it is some combination that is causing the perception of "little people".

Oh that sounds much less fun.

Every time I read about this I find myself asking what the little people are doing, and articles never answer it.

It does?

“ Patients describe colourful figures only a few centimetres tall, marching, dancing and climbing over the furniture.”

Reconsider the blood cell visualization thing. I've had bilateral PVD. Each was accompanied by an initial few minutes of seeing a few dozen small dark spots that had lighter grey centers. Most visible when I looked at the sky. They all disappeared after a few minutes. I think these were RBCs from minimal retinal blood vessel tearing at the PVD events.

Human RBCs are ~6µm - 8µm diameter. Human retinal light sensing cells range from ~0.5µm - 10µm diameter, depending on type and position. They're close packed.

Given the geometry, RBCs leaking onto retinal cells should cast shadows that could be resolved as images. And that's right where leakage is most likely to occur during a PVD event.

Slightly off topic, but on a clear blue sky it's possible to directly visualize the white blood cells running around on your retina. I love watching them go about business, and I think I heard it can even be used diagnostically to do a manual WBC count in extremis for leukoproliferative disease.

They're pretty tiny though, I'm not sure if you'd actually see a center in the RBCs
