II kinds of dreams

'There are two kinds of dreams. In the first, the dreamer can direct the events of the dream as if by magic. He is master of everything that happens or is going to happen. He is demiurge. In the second, the dreamer has no say, he is passive, he suffers from the violence done him from his inability to protect himself. What happens to him is exactly what he doesn't want...'

Andrei Tarkovsky
