If you can control your dreams, you might be hyper-emotional.
The current science of lucid dreaming and how you can learn to do it.
When I was a child, I was constantly plagued by nightmares. Nightmares of being chased by monsters or hunted by “the bad men”. The nightmares were relentless and I was scared of falling asleep. But, one night I realized that if I was killed in the dream, I would merely lay in darkness for a few moments before re-animating in a new dream (I wouldn't actually die).
This conscious awareness was the beginning of my lucid dreaming journey.
Slowly, I learned that I could make magical doors appear and escape the monsters. I could jump off buildings and breathe underwater since this was a dream world and not the real world. If the dream was too horrific to endure, I could even wake myself up by shutting my eyes really tight, then opening them simultaneously in the dream world and the real world. (Although sometimes this would not be successful, resulting in a dream within a dream, like in the Inception movie).
