Weird dream?

So there’s this girl I used to have a massive crush on like I was almost obsessed with her every since 1st grade when I met her up until maybe 9th grade ( I’m out of school now so it’s been about 6 years since I last saw her in person ) Pretty sure she liked me too for a while. We were best friends and even her mom loved me. We would get each other random presents like every other week. We had every class together from 1st to 5th grade. We’d always sit with each other at lunch and in every class and if we couldn’t we’d still try and talk from where ever we were and hangout everywhere else. When we got into middle school we didn’t talk much cause we went to different schools, but in 7th grade she got transferred to my school and I tried to talk to her more but it was just kinda awkward and I never knew what to say. By the time I worked up the courage to ask her out she said she had a bf. So I pretty much gave up. Fast forward a few years later and I find out she’s gay now. Couple more years and I haven’t thought about her since until just last night but only for a second. That night I had a dream about her, I was in class and she showed up out of nowhere and sat next to me, few minutes go by before she says “ is there anything you want to say for closure “ and I say no which is true cause I’ve never lied to her even once or done anything to hurt her. Then for the rest of the dream it was just us hanging out and a bunch of random stuff I can’t remember. What does that mean.
