Some people say that the meaning of life is to be lived. As for the other theme in this article - there is a computer simulation of the known universe, and if you look into details, will see that the whole ting is like a giant consciousness. And a very good picture for example:

It has been proven, that it doesn't matter wether we observe something, or daydream about it - the same areas of our brain are active.

And one more thing. There is a song (ONE of my favorite), named "Never Like this (A dream)", and some lyrics:

This is a dream that I have
A glimpse of a world more real
The night is young, my mind is strong
And I walk of paths so unreal

Maybe there’s more than meets the eye
More to this world than we see
And what if what’s true is a lie?
What if this time I’ll be free?

Oh no! It’s just an illusion
It’s never been like this, been like this
Where do I go from here?
Caged in a moment’s reflection
It’s never been like this, been like this
Been like this, been like this, been like this, like this
