here's an interesting phenomenon, and I was able to repeat the experiment on my kids who got the same effect
when I close my eyes but still try to see as if I'm in a dark room , I can often see lights and shapes, like looking at a far off gas nebula through a telescope. Now when I concentrate on the colour green, the colour of it, or my perception of it at least. shifts to green. likewise, yellow, red. Try it yourself, maybe you can do the same.
I can do this in near absolute darkness. My speculation is that most of our nerve and photo receptors give constant feedback even when unstimulated, but our brains filter out all this unimportant data, except when we consciously force ourselves to be aware of it. Like thinking about the feel of your shoe on your foot, or attempting to see with our eyes closed. Our visual cortex attempts to build a picture anyway out of the bad data, and creates representations of swirls and sparks, but being shit data it's highly suggestable to conscious interpretation. Drugs like LSD play with the brains ability to filter out stimuli, which induce hallucigenic effects as it struggles to interpret increased data normally dampened.

I get the ʾseeing light in a dark room with my eyes closed' thing...
Was aware of the weird kaleidoscopic patterns when pressing on my closed eyelids from an early age...just confirmed I can still do that...

Filtering is certainly part of it.
As is interpreting random stimulation as patterns, whether this is due to our perception making some order of it or possibly related to the ordering of the rods and cones.
Blind (or almost blind) people can sometimes get this disturbing syndrome

Edit: I've had experiences a little like this when dozing
