How can I tell if I am unable to do this? I think maybe I kind of can, but I have to focus really hard and it is a flickering image and I am not sure if I am actually imagining that I am imagining if that makes sense at all. Or the fact that I am not sure is already telling? I don't think I try to imagine anything in my daily regular life though.

Haha, exactly my thought! I can form a mental image (photo) in my mind, but how do I know others can "see" it similarly?

It's not very clear as I can't really see it in front of me, but it's in my head, and there's a different kind of "seeing" happening...

One evening I asked my 5yo daughter that when she imagines something in her head, does she see it almost like in real physical 3d? She said yes. I wouldn't say yes to that question. But again, it's so subjective...
