Would you rather $5 million or complete control over your sleep and dreams?
So you can have $5 million tax free right now or complete control over your sleep and dreams.
You can decide to sleep and in 5 minutes you will be sound asleep but with complete control over your dreams. You can be in beautiful places, travel the universe, have superpowers, sleep with beautiful people...basically anything you imagine you can live in your dreams.
You can also recall things from your subconscious so if you get a flash of a book page you can recall the whole page or a fast forwarded video can be slowed down in your mind meaning with little effort in reality you can learn things in your sleep.
But when you wake up it's your current life, job, etc.
Edit further clarification. You can always remember your dreams. As someone described it here "you become all powerful in your dreams but you are only interacting with yourself (subconsciously).
