>>25342526im actually kind of the same, I CAN visualize an apple or any sort of thing, but only for a couple of seconds until it starts to fade away, however it also has to do with the images registered in the library if your mind, for example I was having trouble so I just went to a super martket and bought some real fruits to look so I could refresh my mind library, and it did help me visualize them for a longer time and in more detail.
