Incest Survivors Support Group
Incest refers to any sexual activity between closely related persons that is illegal or socially taboo. Consensual adult incest is very rare. Incest between adults and prepubescent or adolescent children is a form of child sexual abuse that has been shown to be one of the most extreme forms of childhood trauma. If you or a loved one is a survivor of incest, join the group...

It freaked my parents out and they took me to a children's therapist. The therapist met with me one time and then told my parents there was nothing she could do because I didn't remember the dreams. The abuse started at 5.
By the time I was 10 I had trained myself to go to sleep and to control my dreams. That is when I started visiting the secret room. To this day, I can make myself fall asleep anywhere and then guide my dreams into a place I want them to go. Even when the dream starts going bad, it is like a switch that I flip in my mind and say...nope not going there and turn it into something good.
The door and secret room I believe came about as my escape when I spent weekends at my abusers home.
Side note....really wish that therapist had kept at it. My life might have been so different if she had discovered the abuse then.
