Disturbing dreams!! What the heck do they mean??

I’ve been dating my boyfriend for 6 months, and we’re so in love. He makes me super happy, treats me so good, and is just an overall amazing boyfriend. The only thing is, we haven’t seen eachother in about 4-5 days (which is unusual for us). And I get super anxious when we don’t see eachother/talk for a few days. I over think and feel like we’re gonna “lose our connection”. Which is so not true, because we’ve gone without seeing eachother before, but I can’t help but feel a little bit nervous. Idk why. But anyway, the past few days that we haven’t been together I’ve been having these super disturbing dreams. The first 2 nights I had the exact same dream. I had a dream that I kissed my ex boyfriend (which I dated when I was like 14-don’t even really consider it real) and that I had a figure out a way to tell my now boyfriend. Had the exact same dream the next night. And then LAST NIGHT, I had a dream that I did ~sexual things~ with this girl I go to college with who’s super weird and we never talk!! And in the same dream I made out with my best friend!! (I’m straight btw) when I woke up I literally felt nauseous because I feel like this is so messed up. Do y’all think maybe this is because I’m longing for my boyfriends affection and miss him? We haven’t been able to do anything remotely sexual in the past 2-3 weeks actually. (Except make out). I have extremely strict parents and I have to be super careful. I’m 18 and he’s 19 btw. Someone please give some advice, I’m super freaked out 🥴
