Suggesting, e.g., with grills, some sort of patterned walk. Of course a
driven (encrypting) walk would result in repeated sequences to the extent
that underlying word sequences recurred and the same grill and table were
used.
I wonder from time to time also about what one might call delusional (or
inspired) generation and an underlying mechanism in the VMs. I think
typically something like glossolalia exhibits rather different patterns,
e.g., lots of local repetition, maybe not much long term repetition,
though this is just my hypothesis. I haven't consulted any studies. But
I wonder if there might be other, more mentally involved patterns of
delusional or inspired text generation, in which a person might, for
example, assimilate the text generated, perhaps attributing meaning to
some of it in some degree but never quite reducing it to a system in the
sense of, say, a substitution code for one's regular speech. My
apologies: this is pretty vague and probably not very useful.
