There actually is a way to control your dreams. This is done through our basic senses! When we are dreaming, humans and animals do not experience typical sense sensations while dreams are occurring. Such things that humans and animals do not sense or experience while dreaming is color, light, sound, taste, and touch. Humans and animals also do not experience temperature differences in dreams. As such, when one is about to have a bad dream or a nightmare, one can realize that they are only dreaming and stop the dream quicly if they realize that they are not experiencing any of these sensations.
