This fits way more with my experience than the other comments so far. And as you say, the indistinct form of imagined things is the same in dreams.
There are some differences I can think of with my dreams. One is that of course it really does feel like you're there in a dream. When I imagine something while awake, it's more like a little model surrounded by nothingness in my head.
Another is that in dreams things are often strange, proportions all wrong, just general weirdness. Imagining while awake, you have control over the form.
There are people in this thread saying that they can essentially replace their reality with imagination while awake, "projecting" the scene in front of them. I can't do that, but I can imagine a scene well enough to get by. Maybe there's not so much Normal vs. Aphantasia at all, but a whole spectrum between the two extremes.
