As I was editing and posting this episode it occurred to me that it would be a good idea to point out that our discussion contained elements that some people (maybe even me) are going to question. You will want to pay special attention to at least the following:
1 - Is the phenomenon being discussed here limited to, or primarily about, "imagination"?
2 - At the end of the episode it is stated that the mind does not store images, but patterns.
I think we all agreed that what is under discussion here is the mind's direct receipt of images from outside itself, without going through the eyes, but beyond that conclusions to be drawn seem to me to be challenging, to say the least.
Listen for these issues and I think you will see why we'll probably want to discuss them further.
