ELI5: why does vision turn into a rainbow prism when on LSD?

EDIT: seeing a lot of comments saying it doesn’t actually do that, I’m speaking from my own experience. I’ve microdosed and taken up to 3 tabs at once, it pretty much is guaranteed every time.

LSD is a molecule that is almost like seratonin, but not quite. Seratonin isn't just "the happy hormone", it's a really common molecule used to communicate between neurons. LSD molecules bind to the same receptors in your brain, but because they're a little wrong, they cause your neurons to work kind of wrong, and it results in weird conscious experiences.

It can result in weird sensory hallucinations (visual and auditory), and that's what's usually depicted as trippy rainbow prism stuff. But it also affects other stuff in your brain (which can be positive, or negative). So you shouldn't take it expecting just a fun light show.
