A bunch of scientists believe that there are infinite (or finite) possible universes. They disagree on some of the finer details but they unite in their belief that there is more than what we see. This is the idea of the multiverse or meta-universe (seems a bit of a contradiction to me given that uni- means one). These multiverses contain everything that exists: time, space, energy and stuff. Some science fiction writers like to imagine that there are parallel universes and we can dip in and out of them if we so choose. I do too believe that. I am sure they exist.
Last night I had a weird dream. In this dream I was in the United States and I was due to fly back home via Paris. In this dream, travellers kept their passport and money in a McDonald’s disposable cup full of sand which they buried beneath a designated static caravan. This cup was kept buried until shortly before departure. In my dream I was about to return home. When I came to locate my cup containing my passport and money I found the passport and money to be missing. This meant that getting home would be rather difficult. In the dream, this scenario seemed completely normal and acceptable. I believed that someone must have found my cup and stolen my passport and money. Upon waking, the dream scenario appeared absurd and surreal.
So my weird thought, which came shortly later, runs thus: are dreams actually visits by our subconscious to a parallel universe? Is there a universe where a traveller really does need to bury his or her passport and money in sand in a McDonald’s disposable cub below a designated static caravan? Why not? Perhaps that is completely normal somewhere. Or are dreams just a succession of images, ideas, emotions and sensations that occur involuntarily in the mind during certain stages of sleep? If so, what on earth made me dream that dream?
Believing in the teeny, tiny possibility theory I’d like to think that dreams are the former.
One thing is for certain, next time I go to that universe I’m going to make sure I bury my cup deeper.
