Hey, dont' worry
I also have phases where i dream about this stuff a lot. Often i wake up nauseaus but I never had to v* because of dreams! (Those very few times I have v*d after waking up I had foodpoinsoning and friendly enough, my body waked me up before IT happened, but in these cases I didnt remember dreaming about it..)
I guess it is normal that the feeling you had in a dream stays with you when you wake up. Like sometimes when I dream about my BF cheating on me, i am mad at him the whole morning or even day, bc it felt so real... so when you dream about such triggering things, i guess it is normal that it causes anxiety, which leads (at least in my case) to nausea...
