I get that feeling, it happens to me a lot of the time. I initially didn't know how to control myself in the early days and years. As i grew older i understood things better.

I choose when to stop dreaming the dream once it has become to scary, sometimes i wake up, other times i just switch dreams as i think about changing it...all this is happening in the dream.

I told my dad about it when he was alive and said it is a gift...but what to use it for i don't know.
I love the way you shared yours in light poetic manner. Thanks for sharing.
