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 
The universe wants it just as bad as you do

LOA work for me prefectly, so it can do just the same for you
