According to Osho, dreams are windows into unconscious desires, but what appears is often a censored, substituted version shaped by deep conditioning. Even in sleep or hypnosis, the conscious mind acts as a vigilant censor; taboo wishes are displaced—e.g., desiring the sister becomes chasing her friend—or the dream breaks/wakes you. Reading dreams means looking beyond surface images to the forbidden wish they disguise.
Dreams show what you secretly want, but your trained mind hides it by swapping in safer people and scenes.
