A few years ago wgen i was much more disregulated, emotional, isolated and in general poor health i believed i could hear various historical figures talking to me in my dreams and while i was awake (and conversely me monologuing to them, always one way either them at me or me at them), this has always been a low level thing for me but as a child it was just other schoolkids and teachers and stuff. Anyway it went on to increase in how much it happened and how frequently it appeared outside of just dreams and went from historic figures to religious figures, (interestingly over time it became less and less literary until just strong emotions and concepts would flash into my brain as i looked at them in my minds eye) at a point i converted back to Christianity like i was as a child — gradually the frequency of it happening decreased until one day i realised i hadn't had it in like a year, and i only have it happen with irl people once every half a year or so now and it doesn't feel really like a separate person speaking to ne anymore, idk why really.
