What does this dream mean? Is it just lust? Just a fantasy?

I’ve been having these dreams about a certain guy like it’s happing in real life we had a beautiful future together we was in a relationship, wild passion sex, got married had children I even met his parents. It was fantastic.

The problem is that I’m in a relationship and the guy who I’m dreaming about is my customer and I’ve being seeing him in my shop more.

I can’t stop thinking about my dream guy every-time he comes in my heart skip a beat I’m sweating and honestly I never felt like that before!!!!

And I know I shouldn’t be thinking about my dream guy but I can’t help it.
