I would hear Logan and realize that I was unknowingly co-conscious with him a lot in life. A dream actually did make me realize that he was ore than just a figment of my imagination, though.
It was about a few seconds long. I noticed him floating out of somebody's body. **Trigger warning**
I think it was his own body. He was being raped by some guy and in the dream her floated skyward as if to escape.**Trigger ends** I woke up with a loud gasp and it sounded like a guy. I then began crying because I realized that I wasn't a boy named Logan and that I didn't exist. The next day I became more aware of him being around. I was depressed all day, though and cried a lot. I didn't understand why and it still puzzles me.
Logan has also turned up in another dream of mine in which Logan/I was being scolded by a teacher and we were kind of the same person. It was like, I was me to everyone else, but Logan was with me and we looked like a mixture of both of us.**trigger**
Anyway, he persuaded me to cut in the dream.**end**

But, those are all that I recall dream wise.
I just gradually became aware of Lulu. (The child version of myself. Three years old.) She has been the only one to send me a flash back.
The day before my first therapy session, I had a girl and boy yelling at me and telling me that I was faking. (Two alters that are determined to keep me in denial.) and Hope (another alter) comforted me for about an hour. She always pulls me out of denial.
That's how we all met, though. ^^
