Multiplicity

We always thought of ourselves as sharing the brain just as we share the earth body. Blurring could be like adjacent channel interference on the AM radio. You're listening to one station and you start hearing another station in the backgroun, sometimes loud enough to drown the first station out. This is causded by either atmospheric conditions or the second station has boosted its signal for late night broadcasting. DX radio listeners know about this. (Stay up real late listening to AM radio, try to hear Chicago when you're in Lexington, that sort of thing)
