People sharing their experiences here is very interesting and I wanted to do the same to see if others are similar as my experience is different than most people discussing aphantasia/hyperphantasia.

If I'm using the stickied post on this sub to characterize my experience, I definitely have aphantasia. If I close my eyes and try to visualize I never get more than a black screen.

However, my imagination is quite vivid. Nothing I imagine is ever overlaid on top of my visual field in any way, but I can still 'see' it clearly, with colors, movements, sounds and touch (smell and taste is something I have to focus on a little more). I can manipulate every aspect at will and focus on specific aspects as I wish. This is always how I interpreted the 'mind's eye' as being different from my actual sense of sight, but it seems most people experience it as physically seeing. It's difficult to describe because it feels like a whole other sense, a sense of imagination or something. I don't experience these imaginations as anything less than full scenes and not just words or impressions.

I definitely don't feel like I have aphantasia, but going by the given definition, I do. It seems to me, there's a difference in being able to imagine things vividly and the degree of overlap it has with our physical senses. This degree of overlap I think is something completely separate but we use it to define aphantasia/hyperphantasia.
