You are invited to a lecture. You know that the subject is probably important and it would be useful to hear what the speaker has to say but you can't keep your eyes open. You will fall asleep and you will dream. But you won't be alone in your dream; everyone else will be there with you. And you will have a chaperone who knows the landscape and will attend to you. So nothing can go wrong...unless...no...just close your eyes.
