Also, I've had a bit of an epiphany for the "symbols" said to be characteristic of Ni-types. This always confused me because I thought it was literally seeing a still-image symbol for something, when in fact my symbols are like video bits. I don't always know what they mean, but they feel heavier and more pronounced than other forms of thought when I think about them. I have one prominent one right now where there is a dark figure, who I know is me, facing away from my point of view, as if I'm looking at my own shadowed back, and then about 3 seconds an even darker person comes out of the foreground and puts a hand (the entire arm is colored, but nothing else other than the light-bluish foreground and darker blue background) on the top portion of my back. Since the purpose of this thread is to demystify Ni, I need to explain that I can dissect the "video-bit" (meaning that it isn't some ridiculous vision) which is more like a product of my imagination anyways (everyone can make a simulation in their imagination). I don't know what it symbolizes right now, but I have some ideas.
Interestingly, when I change something with my mind's eye about the simulation/video, it doesn't feel right; for instance, trying to illuminate who the darker figure is by filling in the spaces with random people yields an "uncomfortable" result, and it feels more right if I imagine the figure like it originally was, shrouded.
