''when you were sleeping,whatever that happened during the sleep was reality for you at that point of time''
Mind boggling!
I'm not sure if you can call this fixed or not..
We all know that when we fall asleep we are perceived as the most vulnerable to anything..
Hence our minds open more freely in this 'unconscious' state and we can think of anything in the world..
We dream about flying, we dream about being an Oscar winning actor/actress, we dream about being with some lover and other x-rated stuff, we dream about being super heroes, etc.
It is never ending..
I dont think these dreams or this 'fake reality' is fixed..
Its not like you actually want to fly, or maybe we all do, but still, you know in truth, that it is impossible to fly, without some hi-tech gadget, but does your inner self, that comes out during a dream know that? Because all that inner self will dream about is only you, without any machinery or anything else, soaring above the clouds..
Some people also say that whatever happens in dreams, is related to reality, like, a person who dreams of a certain object, actually wants that object in real life..
Again this is not proven whether we actually dream of what we want or secretly crave..
For example, when I was younger, I remember vaguely always dreaming of a crocodile, a ferocious one.. But at that age I had never even seen a crocodile, I hardly watched Discovery and my local zoo did not have them.. Why I dreamed of it, I cant really say..
And it was a recurring dream..
Another recurring dream, about 2 years ago was 'the world is ending' sort of one, with me stranded on a bridge with the water levels increasing from underneath and the entire city wiped out
Most of the times I realize that I had a lovely dream, but I cant seem to remember anything about it!
So at the moment, our dreams are mostly far from reality.
I guess you are almost right to say that what happened in a dream was actually a reality at one time, but it is a reality in your sub-conscious mind, not in this physical word..
Who knows, maybe we might actually wake up when we die, and realize all of this - our families-school-yahoo-Europe- every damn thing was just one big dream..
Could happen, but we would never really know unless we die right?
We are still dreaming then..!
