Actually the answer is no

I think this is probably the most common misconception people have when thinking about Truth/God/Absolute/Enlightenment, that it is a visionary experience in itself because we are so used to associating what we can see with what we believe reality to be. This is further solidified by all our scientific concepts about matter and the physical universe, we have this intellectual foundation that is very bound to the perception of sight and spatial dimensions. Understandably so, of course.
That's not to say you won't experience visions or mystical states along the way. I think anyone who pursues this sort of thing is bound to experience at least lucid dreaming, which is a visionary state, and perhaps an astral type experience (very similar to NN-DMT). But the actual realization itself is not a visual thing because it is to do with that which is perceiving, and not that which is perceived. Again going back to the lucid dreaming metaphor, once you experience a fully lucid dream you sort of get it.. that the dreams themselves are not actually that important, what is imminently more important is that which is now immediate and obvious.. which is 'you'. Up until the point you have a fully lucid dream it is a bit like trying to describe colour to a blind man, it's something you have to experience directly and then you really 'get it'.
It's impossible to describe such a thing as realisation, because you can't describe something that is
not. Imagination can't conceive of it and language can't convey it, because anything that they come up with will forever be not it. It's like trying to describe what empty space objectively is.. it has no actual properties, and whilst you can use various concepts and language to relay what we think it is they still don't actually describe
what it is.. it's impossible because it is absence. How can you describe absence of falsehood about yourself? I can do it for myself but it will be utterly meaningless to everyone else - paradoxically those with strong intuition, or who have had similar direct experiences, may be able to pick it up through the language though.
Who can say? Everyone is at differing stages of ripeness. Even then it's not necessarily a linear or predictable thing, the only predictable thing is that you will succeed if you want to succeed.
