I think you have the right idea Minyan- I don't think there's anything wrong with sharing one's own experiences, especially if it gives someone who is learning something to validate their experiences, and maybe help getting there.
And it is also true that teachers don't necessarily want students to think that the phenomena is 'what they're here to learn' also. I have my own idea of why the peripheral sight works better than straight ahead, but it's just an idea.
