I think we can feel and create temperatures more or less in our mind because our mind has nerves, and nerves are what cause the feeling, even if it is a fake one. As for the images, we do NOT create them, our brain uses what it has seen only. Seeing images or events used at random to create an image we can see by feeling it. As toughts are in a way just nerves, and we actually are feeling the images, not really seeing them. Because what we see is the computer (for example). But what we feel and in a blurry way see are nerves.
our minds have a storage area allowing specific memories in a thoughts notice. I'm an artist, and I've self taught myself illusions of lined art, and I've got to say, we see things because our minds will logically put memories together . so quite literally, what you see in my drawings, might not be visible to someone else.
