i dissociate all the time when talking.
there are a bunch of us inside, and switch a lot, and often finish each others sentences or when one finishes a sentence it might remind someone else of something and so then they will start talking about that thing, which reminds someone of something else. or maybe we all have different opinions on the same thing, so we switch while talking to all give our opinions. or to respond to each other.it sounds lik free association maybe, just woth different voices.
for instance:
#1 i might say i like a beautiful flower i just saw.
#2 says i like it too
#3 says i dont really like that color. i like flowers that are purple.
#4 says: you like anything thats purple
#5 well its my favorite color
#1 says Can i just finished my sentence?
#3 i thought you were finished
#2 what were we talking about?
etc etc
