@bellinitte Ohh that's really interesting! Did you write them down? If not, write them down in the first person, present tense...eg. "I'm in a room doing _______ and suddenly from the corner of my eye I see this guy, he's wearing glasses and he says____" etc. And draw any images of what he's doing etc. See what riddles or metaphors come up, and note what he does/says. See if there's a theme.
@bellinitte And note what the vibe is, what kind of feelings or atmospheres surround him etc?
Or maybe you'll see this person IRL? That's happened to me before, only after one dream though.
