How is my dream possible?

Two days ago I had the weirdest dream ever. What happened in it was quite normal, I was hanging out with my friends doing regular dream stuff,
What was strange however is that I don’t really have those friends. They were loosely based on my classmates from middle school but in real life I have never hanged out with them.
But in my dream I had memories of countless memories with them, like if I knew them my entire life. The memories remained after I woke up and for half an hour I believed they were my real friends. That everything we did really happened. It was later when I found that I don’t have any conversations with them on Facebook and I don’t even know them. But I still had fuckton of memories with them. Not from the dream but from before the dream.
I don’t know if that makes any sense it’s really hard to explain. This expierence really changed me in a way. I just don’t understand what happened and how was my brain able to create so many memories and put them where real ones are. All in a matter of 4 hours when I was sleeping.
