dream in a dream?!.. Waking up from a horrific dream scared out of my mind..

I woke up few hours ago with my heart beating very fast, hyperventilating and shaking. It took me awhile to calm down and then call my best friend who the only one I told about my past but she doesn't understand why I'm so scared and she told me to just pray and I tried but It didn't help. She says no one can hurt me here and it is true but I still can't relax.

I dreamt of being in some kind of an amusement park and I was terrified for no reason, I remember stepping on a ride only to have my aunt yell at me to get off and that the ride is close for the public and only specific people can go on it.

The place was filled with people who all reminded me of childhood trauma, there was this man who I strongly dislike commented on my cloths but I was covered from head to toe and he said something I don't remember but I remember shivering and wrapping my arms around myself and running up some stairs but somehow I ended up in a room full of men reminding me of the one who abused me as a child with my sister suddenly making an appearance and then I woke up glad that it was only a dream but I didn't really wake up, it was a dream in a dream and it makes no sense to me.

Anyway, I was in my room with my door locked like it is in real life, I was thinking that I just woke up from a horrible dream but then my room door started opining and I started panicking because my door was locked and it is impossible for anyone to get in. I couldn't see anyone but I recognized a figure that looked like a woman, she sat near my feet but I couldn't see her, I tried to move but I couldn't and all I was doing was asking questions and I remember her telling me its ok and not to be scared and that she has a key then I felt a hand on my leg going upwards and I remember yelling and crying for her to stop but I couldn't move my limbs so I closed my eyes really tight and started telling myself its a nightmare and that it will go away if I just woke up and when I did open my eyes I was in my room alone and scared out of my mind not knowing what just happened.. I have a history of childhood sexual abuse and the abusers were male and family friends so I don't understand why I dreamt of a woman.

I don't know if this has to do with anything but for the last two weeks I've been dreaming about Iron Man and I have no idea why, I don't like him much and I watched the movies thinking it will help but for some reason I still keep dreaming about him and then that horrific nightmare happened out of the blue.
it has been a while since my last nightmare so I don't get this one.

A lot of time dreams of being immobile or significant of a fear of being trapped, as well as being to rigid with your emotions. This tells me that your past seems to still cause you some significant stress.

I have also had dreams where I dreamed that I woke up and then it turned out to be still a dream. I hope you don't have this dream again. I can't articulate what I feel about it, just want to tell you that I care.
