I can visualize pretty well I think but I'm somewhere between purple and blue, I need some internal monologue to get started, I describe what I want and then it appears, once it's there I can see details that I didn't describe, then I start "editing" until it appeals to me.
I can easily get carried away, I remembered the last time we had an aphantasia thread I visualized a beautiful beach so I recreated that and went back there, then I thought about what it would be like to be part of a study on that topic so I visualized being in a researcher's office visualizing being on the beach, so now I was on the beach adding the village that's a few hundred meters in the distance on the right and also had a conversation with the researcher who kept asking questions which was super annyoing but then I felt bad because I had agreed to take part in this and knew he'd be asking questions, he was also kinda cute.
Then I realized it had been ten minutes with me wasting time on the beach and I hadn't even fully decorated the office, so I started adding some plants, stuff on his desk, pictures on the walls, curtains, a shelf full of books, his coat and a shoe rack next to the door (don't ask me why he has a shoe rack in his office, he just does).
Then I remembered I actually wanted to write a post here, I can easily spend half a day doing nothing but lying on the couch imagining things.
