Weird confrontation

I had a dream last night that was kinda weird. It started with my in a library studying for school. Then a girl I had a mini crush on( liked her for like a couple weeks, haven't really thought much about her lately) sat across the table from me. I didn't say much, but out of nowhere my grandma shows up telling her she is taking me and my nieces to the zoo, and asked her if she wanted to join us. My grandma then left, and I said she is more than welcome to go with us. She said yea, and she looked like she was holding back tears. I asked her if she was alright, but she just said yea. Then some guy took her a little bit away and was kinda yelling at her, and she comes back saying he wanted totalk to me. So I go over and he says she's not going anywhere with me, and don't talk to her again. I say back that she can talk to whoever she wants and can go with us if she wants to.

That's all I really remember, I didn't know the guy or anything, so does anyone have any ideas if this dream is supposed to mean anything?

Wow. So, is this guy her boyfriend?

That probably would've been a good part to add lol. No, I don't think it was a boyfriend, I wanna say it was like she was famous or something and he was a manager or agent or something like that, focussed more on her career rather than what she wanted to do outside of that. Hope that clears it up
