Peace to the Gods and Goddesses of Planet Ki (let’s make sure we are using that proper greeting that was taught to us)
in my dreams eye asked the people if they were projections of me or spirits and they answered spirits as if they had waited forever for me to figure that out...they may not be the people they impersonate it can be any of these 3 theories
they really are the people we knew in this life but lost contact with and turns out they actually died
Or they are the energy from those people from the interactions you had with them and a part of their spirit stayed with you
Or they are spirits impersonating the people you have met to better make use of the lessons they try to teach you through your dreams
