Yes i do believe she is entering my dreams, and yes i cant tell if im not just dreaming this up. I can't 'wake up' In my dreams. i've tried to have lucid dreams before, but i haven't really put much effort other than keeping a journal.

She is or was a friend i use to hang out with, but i quit hangin with her because she was 'weird' Mostly because i thought she was using my dreams for whatever reason she wanted. I never confronted her about it cause i was more afraid that she would do something. I've asked for help before and was told to break off all connection and that would make it stop if she really was doing this.

I've looked into dream signs and stuff to see what the common symptoms are for things like, being naked in a dream, or seeing parts of myself mutilated. This is usually what happens when i see her or around the time when i see her. What all can someone do who is a master at this kind of stuff? Last dream i had she made me take a pill, i cant remember how it tasted but i ran to the sink to throw up. I cant remember everything that happens tho... I looked in the mirror and saw my father being chewed out by one of her friends. So i threw him down and started punching them. Asking things like why? And getting a response about people not being able to live their lives because of limitations/restrictions put on them by society? Like im going crazy!
I had my suspicions but when once i tried to stay focused on her while she was asking me some questions. Its like she can tell when im conscious cause she'll say something like ".... and a distraction" then something bizarre will happen. Like a car completely decked out in flashing lights or they just walk into a room that i didnt see before and then their gone like that. Thats when i started to believe she wasn't just another dream character.
