Dreamt i was a girl

So I had a weird dream with a convoluted plot. It eventually lead to me being asked by a guy to have sex with me. And when I agreed, I realized I was a girl. I had a vagina, and the penetration felt very real. It was a mind blowing orgasm. It was so powerful I woke up mid orgasm and moaned the moment I woke up. It did not feel like a typical orgasm, I felt the penetration and it was a very powerful feeling. Is this normal?!?
