Is it normal to still dream about your first ex after 5 years of separating?

I was in a long-distance relationship for a couple of years with this guy when I was just graduating high school (he was a year above me, in college then), and now I'm graduating college. We broke it off because we decided long distance was too much for us at the time.

Now, I have a cat with my boyfriend. His friends and family love me, and him and I get along well (for the most part). However, I go through phases where my ex appears in my dreams over and over again. Just us being together in some random setting, but they kind of romanticize him---enough to make me not want to wake up from the dream. He has his flaws and I don't think of him often, but now he's cycling through my mind again. Is this crazy? Am I not over him? It feels like so long ago, but it's making me question the integrity of my current relationship. Thank you for any thoughts/advice.
