If, when you lay your head upon your pillow tonight, you could choose to slip into a dream dimension where time would literally expand, so much so that you could live out an entire other lifetime within it as a person "designed" by you from head to toe, even choosing your name and who your parents would be. Where every single day you'd be pushed on to greatness, every single challenge would invite you to become more, and all of your dreams could come true. Where, no matter how things may ever seem, you'd be bathed in love, surrounded by friends, safe and sound in your very own bed. And where, upon waking, all that you loved and learned in that lifetime would remain with you, and all that scared and threatened you would only have prepared you for even more love and learning in the near future.
Would you choose to go there, just for one night, on the condition that during the dream itself you mustn't have any recollection of how you got there, its purpose, or what might happen next?
Of course you would, you're a supercoolhappylovething!
Which begs the question, "How do you know, then, this isn't that dream?"
