My imagination is not the best, but when I am really high on marijuana and I close my eyes, I can imagine alls sorts of absolutely gorgeously bright and photorealistic visuals. I can imagine anything with remarkable photorealism during that state of mind. It's semi autopilot and spontaneous, though. My imagination also becomes very strong right before I'm about to fall asleep. When I'm sober, my imagination takes effort and is hazier, and not creative. I also want to ask people with Aphantasia, what do their dreams look like?

Our dreams are the same. Dreaming actually activates the visual cortex, so it doesn't depend on imagination. We also get hypnagogia.
>Dreaming actually activates the visual cortex, so it doesn't depend on imagination. I thought imagination also depended on the visual cortex. Dreaming and imagining is not too different to me. One is a bit more conscious, that's it.
As I understand it, aphantasia relates to a lack of coordination between different parts of the brain that allows that activation to happen while awake. There hasn't been a ton of research into aphantasia yet, so take that with a grain of salt, but during discussions with other people with aphantasia I have never heard of one of us not being able to dream. Psychedelics work too.
