When you wake up in the morning and look outside, do you see the same picture? Do you hear the same sounds? It is possible, if you window is just 3 feet away from a brick wall, and is completely sound proof. 

It is also possible if you built an imaginary wall around yourself, and you simply don’t see the surrounding World. Because I don’t believe it is possible to have two identical days, or even two identical seconds. Clouds will be different. Birds will be different. Flies, butterflies, bugs, crickets will all be different. My friends, every moment is unique, unless you are staring at the imaginary wall around yourself.
