One encouraging thing to say on the subject of parallel universes is that you don’t stand the remotest chance of understanding it. You can say, “What” and “Eh?” and even go cross-eyed and start to blither without fear of making a fool of yourself.
The first thing to realize about parallel universes is that they are not parallel.
Please feel free to blither now.
