I wasn't sure if I should put this in the abuse forum or here, but I think the focus isn't so much the abuse itself, but my PTSD symptoms going on with it.

Last night I had a disturbing "dream", in this "dream" I was still in high school and I was waiting after school to be picked up by my mom, but she was running late. (I mean, so late that it was dark outside) My school was close to a lot of stores, so I told my teacher that I'd go to some of the stores and ask the strangers if I could catch a ride from them. My teacher offered to drive me home, himself. So I get in his car and instead of driving me home he drove me to an empty parking lot.

As if that wasn't already disturbing, from there he starts to threaten me and say if I don't have sex with him, he'll never take me home. So, in my "dream" I had sex with him and it was so graphic and it felt so real I felt stuck in my dream and when I woke up I felt even worse.

Now, I have never, EVER been in a car, alone with a teacher before, so I know that wasn't at all true. But could the memories of the "sex" be a part of a flashback that's manifesting itself in my dreams? This isn't the only dream I've had like this lately, it's been happening quite frequently. But, it just felt so real, the "sex" I mean.

I'm a little scared to go to sleep because I don't want to have anymore dreams like that. It took me YEARS to get to this point in life where I'm no longer afraid of sex, but this nightmare... I think it just made me take twenty steps back. I feel disgusting thinking about it, it makes me feel horrible about sex and it makes me feel horrible about everything.

I guess what I my question/point is...
What am I supposed to do? Was this just a silly old nightmare, or is it probably related to my PTSD? And what is one supposed to do about feeling sick to their stomach when thinking about sex? Lately, before all these "dreams" started, I was feeling pretty comfortable with sex, but now it's not comfortable anymore.
