we are spirit in a human body and not a body with a spirit. therefore spirit is always reality. spirit works through the body, but also without the body, as in a dream. the world in dreams is therefore as real as our daylife reality. you can always keep the controll in dreams & create the dream you want, with a technique that is called clear dream or lucid dream - you are conciouss about the fact that you dream - so you are in daily life. but here the controll and conciousness is much weaker. therefore in the world of dreams we are more connected with our true nature.
