alt Hacker NewsThe people who question this usually turn out to clearly have aphantasia.
As I've mentioned elsewhere, I have achieved visualisation during meditation, once.
I also can visualise while dreaming.
I do not visualise while awake other than that one time.
The difference is extremely stark and very obvious.
I really don't think this is the right definition. I don't think I have aphantasia: I picture things in my mind's eye, can manipulate those images, and I get the various stimulus responses described in some of the literature. But it's totally different than dreaming: it's an act of will, I can dismiss it at any time, and I would never be able to convince myself I was actually 'seeing' what I imagined.
But heck, if that's it then hail, brother.
