I really need help!!!

Anemone

So basically Me and this guy have been super into each other for almost 7 months, we say I love you to each other and all that jazz but we’re not officially dating because both of our parents are weird. (I’m 17 by the way and never been in a relationship). About 3 or 4 times in the last 2 months I’ve had dreams that are similar. It starts with me seeing some random guy that I think is attractive, ( one of which was a celebrity crush🤦🏼‍♀️) and I end up in these super sexual situations with them and dream me wants to see where it goes so bad but the whole time I keep thinking about my mans and how sad and terrible it would be if I cheated on him so dream me always says “I can’t do this” and just gets the hell out of there and wakes up feeling super guilty. I’ve tried looking it up and I just really need to know what they mean and if someone can help me.
