I figured since you'd never experienced it, I'd try to explain what it's like to you. For reasons I don't exactly understand, you keep trying to tell me what it's like instead! To compare it to a hallucination is a bad analogy, to compare it to an imaginary friend is an even worse one.

You have abstract thoughts, they just seem to lack a conscious visual component, but that's all the "mind's eye" is, thoughts. There's a distinct difference between your thinking and your physical experience.
