According to Osho, samsara is the dreamlike story the mind spins - desire, fantasy and fear - so convincing we act on it and suffer. Like the tramp who 'moves over' in a fantasy and falls into the Thames, we live asleep in projections. Awakening, seeing through the story with awareness, ends the hypnotic spell and frees us from unnecessary misery.
Samsara is like dreaming you're in a warm mansion while you're really on a cold riverbank - if you believe the dream and roll over, you splash into the water.
