BlindFilmCritic, who has been blind from birth (by the way, a wonderful character, I recommend watching his video), talks about what people who are blind from birth experience under the influence of psychedelics: youtu.be
To summarize, their brains never did not see and he cannot imagine what it is like to see with his eyes. Under the influence of psychedelics, as well as in a dream, the brain can work only with the information it possesses, which means that all kinds of hallucinations are possible only in terms of sounds or, for example, tactile sensations.
Hmm, well, the question is very close to the question "Can the blind see dreams?" Yes, they can, but because they do not see, they dream about smells, sounds, tactile sensations, etc. etc.
So I guess it's the same with LSD.
