There’s not necessarily any message. Often times characters in our dreams are not who they look like. The characters stand for sides of yourself. So this could be more about being “intimate” with some part of yourself than anything else.
I can tell you for virtual certainty that this is not a message from this person. As far as I know, there has never been a single shred of evidence for mind reading. That’s what would have to happen for the person to appear in your dreams.
These dreams are about intimacy, I think. But, unless you know this person well in real life, the dreams are not about intimacy with the person you don’t think about.
If you know the person well, then the dreams can be wishful thinking. I.e., a sign from your subconscious that you are interested in this person. It is not, as I said, a sign from the other person.
