What does my dream even mean?

So, I just had this weird dream. I remember arranging books in my algebra class with several others. They seemed strange but familiar at the same time. I decided to flip over one of the books to see what type of book it is. And of course, it wasn’t books for algebra but a book about philosophy. Once I was done arranging the books, I sat down and a man turned around from his seat to look at me. This man seemed very familiar but I can’t put my finger on who he was. His eyes were glowing red and he told me,
“Appreciate the things you have before they all disappear.”
Everything turned black and then I can see a faint memory of that same man holding me in his arms.
He whispered, “Love me before it’s too late.”
The man let go of me and smiled before disappearing. Memories that I never had started to unfold before me. He was hugging me, smiling at me, and holding my hand while warmly gazing at me. I woke up crying and there was an overwhelming feeling in my chest.

I don't even know why I had that dream. I've never had a significant other-
