Allow me to assure you that you do not want to awaken in mid-air, traveling in open atmosphere through your bedroom or while smacking into the floor and skidding to a stop on your now badly scraped hands and knees, without the slightest recollection of -why you are physically flying in the air when you were supposed to be sleeping-. This is the kind of thing that, really, you do not need to contend with. Ever.
