Strange sex dream

I had a dream last night that I lost my virginity to my first ever boyfriend.

The weird thing is is that him and I were together for just a month when I was 18 and we never had sex. I haven’t seen him since then (I’m 22 now)

I waited until I was in a better relationship tbh. Fast forward a couple years and now I’m in a year long relationship w my current boyfriend

So obviously him and I have sex.

I just wamt to know why a guy that I haven’t even thought of in years showed up in my dream taking my virginity when I’m no longer a virgin??

Can someone explain lol
