Yeah it isn't so much conjuring new concepts as it is that the hallucinating mind connects existing concepts in ways never experienced before. So someone would never normally connect the concept of their self identity with the concept of a glass of orange juice while sober, but while high on LSD this could seem like a plausible scenario, and the synaptic connections made during that trip can persist afterward and leave a lingering sense of bizarre connection. I read a very interesting piece on the use of LSD by creative people and how some felt they benefited immensely from taking LSD precisely because of those random connections that they formed between mental concepts that they had. The basic theory was that creative people in these scenarios had minds full of concepts that would tend to work well together and could benefit because there was a high probability that the connections that formed were valuable and useful ones.
