When I was five, I had a dream that was just blackness with some object that I was playing with. I woke up. I wanted to go back into the dream and take that thing out when I wake up again. Somehow, I forced my self to sleep in less than a second and resumed the exact same dream. I strangled the shit out of the object and I woke up again. I figured it was impossible from that point on.
I used to have a lot of nightmare and scary dreams before the age of 8 but after that I could control them and ever since I have been able to. I feel though that my ability when I was younger was better than it now is. But I remember having superman dreams and also I used to sing in my sleep and my dad used to get annoyed as I would be too loud.
