Other girls in the dream, cheating on GF?

The last one or two weeks I've had some dreams where there is hot girls that I'm close to bang.
Last night I'd a dream where I was in my girlfriends kitchen, then there was two girls who I always thought was completely nerds, but now they were super dirty and I somehow just wanted it....
It feels like I'm cheating on my girlfriend in my dreams, because I'm almost banging other girls even though in the dream I know I've a girlfriend because I see her in the dream or I'm at her place or something about her.

I love my girlfriend and I wouldn't cheat on her.

What may this dreams mean?

Humans are animals, and our primal instinct of sexual attraction will not magically disappears as soon as we enter a relationship. If anything, it would be odd if you didn't fantasize about having sex with other girls.

Don't worry about it.

Hmm alright
