Weirdest sex dream? Can anyone relate

Hey so I’m a 21F, and I’ve literally just woken up this morning from this really intense vivid sex dream. As in it felt like I was right there. In this dream, it was a massive castle and it was like a fantasy kind of kingdom but also realistic and there was this princess. For some reason I was a MAN and I was a king and I knew I was a man because I had a cock.

And this princess was in her room avoiding me for some reason so I went there and I literally in this dream omg started kissing her neck, chest and like her lips and it was so realistic that my male cock was literally throbbing and imagine at the moment it was getting super intense. I woke up MYSELF in real life from the dream. It was like a long breath type of wake up like it was like the air was coming back to me. Bruh I had to pee straight away I feel like I had an orgasm because it was what woke me up.

Can anyone explain to me why I was a male, why did I fuck a woman and why was this dream so real. I’m actually kinda scared.

ALSO DISCLAIMER: before you put an image to me I’m literally a 21 year old female, I’m a virgin and I like men. (Straight)!

Also makes it weird as I’m a virgin and I can imagine sex like this😭😭😭😭😭bro I WAS A MANNN HELP. Can someone please tell me why tf I was kissing and sucking another woman’s neck and why it was so realistic. Like it genuinely feels like I was there I cannot explain it.
