RS has an influence on the other person, you are basically making him dream about you, so there is a possibility that he is unconsciously doing the same thing. Or its a part of your manifestation, its getting more of what you want. Both possibilities are great so keep doing it. I also have this kind of dreams when I am doing RS and I know for sure that the guy I am attracting has those too, because we started texting and when I do RS, he texts me almost instantly and gets more flirty
