Dream Or Nightmare?

In the thick of the night, with your eyes closed tight, a dark figure approaches... but don't worry, he won't bite. That is, at least not with his teeth. It's The Sandman and he's come to bring you a dream. As he enters the tangled web of your slumbering mind, will he render your hallucinations cruel or kind? Will you be lifted from sleep wishing it all came true, or will you rouse in cold sweat feeling black and blue? He feeds off your inner hopes and fears, though the line between dream and nightmare is not always clear. As he envelops your brain with glowing grains, and choreographs your imagination's midnight dance, will you be able to tell the illusory difference?
