Well, dreams are doorways. And having a dual existence is the surest way of burning your soul out.
My sis-in-law was watching me pad around and stated I must have been a cat. She must be onto something there, 'cause cats love me. (Most dogs love me as well, but it's more like "Oh Boy! Playtime! Borp, snort snarf, slobber!")
If I did have parallel lives, I'd be surprised to meet myself. And probably would meet me somewhere... knowing me. *Shivers*
We'll send Shivering Jemmy of the Shallow Brigade!
