I don’t follow the research here but I was pretty sure it was a joke at first because after the initial quote (preceded by the statement “ Consider the statements below. What do they describe? A trip on psychedelics? A dream?”):

> I felt I could reach through the screen to get to another place. Lasers became entire fans of light sweeping around, and then it felt as if the screen began to expand. I saw old stone buildings … like a castle … I was flying above it.

I was presented with 3 options, a Dodge Ram, a Jeep Grand Cherokee, and some other truck. I was trying really hard to figure out what the statement had to do with vehicles until I scrolled down (on mobile) more to realize it was a poorly placed advertisement. Not sure why the internet thinks I want to buy a truck, but I imagine there could have been even more hilarious things that could have fit the context better.

Hmm, no wikipedia page for "ganzflicker", and 90% of the google hits are dubious websites. However, I will be trying this tonight because I loves me a good hallucination and if it can be done by sitting in a dark room staring at a flickering screen for 10 minutes, it sure beats acid.

It would be fun if this ends up being just a test of how suggestible or easily influenced people are.

I'm with you, sorry, I don't believe you can see shit in a flashing screen. Aphantasia seems like a popular self-diagnosis.
