So I was watching this youtube video (it's bach's toccata and fugue in D minor)
And when it was done I was having effects on my vision similar to that of watching one of those "natural hallucinogen" videos.
Here's an example.
Why did my vision do this?? Why does it do it on the other video? Something about straining the muscles (or w/e) in your eye or something from constant change?
"If a topic that clearly interest noone needs to be closed to underline the "we don't want this here" message, is up to debate."
How should I say this....in your brain there is a section that constantly makes unconscious decisions for you so that you don't have to think all the time, stuff like whether to use your left leg or right leg for your next step, stuff like that. The problem is, this section can easily be fooled, and when you stare at that video, it thinks that you are actually walking towards the center point of the hallucination, so it merges the circle and the part outside together so that you won't "get dizzy as you walk". As for why you see weird stuff when looking away, that's because that section knows that when walking somewhere, you would get sidetracked and look away at sth too, so even when you look away, it still maintains that state for awhile so that "you won't get dizzy when you stop looking away and look back forward and continue walking" (or so it thinks)
If you stare at scrolling credits at the end of a movie, then sometimes your vision can get tricked like that too, and when you look away you can see the scene (that you're looking at) slowly rise upwards.
