The nature of consciousness

Let's suppose you were able, every night, to dream any dream you wanted to dream, and that you could for example have the power to dream in one night 75 years worth of time.
Or any length of time you wanted to have.
And you would, naturally, as you began on this adventure of dreams, fulfill all your wishes. You would have every kind of pleasure you could conceive. And after several nights of 75 years of total pleasure each, you would say 'Well, that was pretty great.

But now let's have a surprise. Let's have a dream which isn't under control, where something is going to happen to me that I don't know what it's going to be.'

And you would dig that, and come out of it and say 'That was a close shave, now wasn't it?'
Then you would get more and more adventurous, and you would make further and further gambles as to what you would dream, and finally you would dream where you are now.
You would dream the dream of the life that you are actually living today.

Alan Watts
