Normal waking consciousness, dream states, emotional states, and other states of awareness are different realities, somewhat like channels of the TV receiver.
As you walk down the street you can tune your "receiver" into the world on any number of channels. Each way of tuning creates a very different street, but the street doesn't change; you do. You see what you look for. If you are primarily preoccupied or tuned to the physical body, as you look at people you see them as man or woman, fat or thin, tall or short, attractive or unattractive. When you are busy looking at personalities you might see them as introverted or extroverted, hysterical or paranoid, happy or sad. If you were tuned to the astral identities you'd see a Leo or a Taurus, an angel or a demon. It's all in the eyes of the beholder. Christ could walk up to you and you might see him as a pleasant carpenter, dressed plainly. You might think: interesting teacher, he has a nice vibe. If you were looking beyond that, you might see Him as Living Spirit.
