I've encountered different people in my dreams that apparently, I knew. Like if that person was part of my life, I knew their background stories, personality, my relationship with them, everything.

For example, I had a dream in where I was running from an old man with a white haired young girl, our relationship was short, I only knew her for a few days but I knew what we were doing (sadly, those memories vanished upon waking) I remember that my father was with that man and told me to give them the girl, that she was a witch or something, so I felt this urgue to protect her because of our friendship, I really felt sorry for her, I was sad that she was being persecuted. Then I woke and realised this person isn't real, the feelings I felt in the dream were gone, and so were the memories, I don't even remember her name.

Does anyone else experience these things? it's pretty interesting to remember these kind of dream characters while awake.
