i have also had many dreams about people from the past, people that i have not seen whatsoever. i've had these dreams for the past 2 months... really weird. people that i have not even physically seen for about 10-15 years in my dreams all over the place, and many many people too.
i just noticed with the liver pumping that every once in a while after the pumping i would start getting more relaxed. then when another round of pumping came, more relaxed... and so on. i don't liver pump for 2 hours and cannot stay awake more than 1/2 hour to an hour.
at least it's good that you can sleep even though the liver pumping keeps you awake for a while.
