Encephalitis lethargica, also known as "von Economo disease" or "sleepy/sleeping sickness," is an atypical form of encephalitis which attacks the brain and leaves the victim speechless and motionless. An epidemic spread around the world between 1915 and 1926, and isolated cases still occur. Not to be confused with the "sleeping sickness" trypanosomiasis, transmitted by the tsetse fly.

Also known as the Liber Paginarum Fulvarum (Latin for "Book of Yellow Pages") or Necrotelecomnicon, this book is a shared joke between Gaiman and fellow author Terry Pratchett.
It also appears in Pratchett's Discworld series and the book Good Omens, which was co-authored by Pratchett and Gaiman. The Necrotelecomnicon of the Discworld is a list of all the old, dark gods, and this Paginarum Fulvarum seems to have the same function.
When Gaiman was first asked to write a Sandman series, it was intended to be a revival of DC Comics' series from the 1970s. The original Sandman, Wesley Dodds, dated from 1939. A man who used sleeping gas to incapacitate criminals, he left sand at the scene as his calling card.
When it was decided that Gaiman's series would take an entirely new approach, Gaiman's solution to the dilemma of having two Sandmen in the DC universe was to show how Wesley Dodds had been indirectly inspired by the immortal and ancient Sandman, Dream.
Dream's helm was designed to resemble the World War I gas mask Dodds wears to protect him from his own sleeping gas.
Kundalini yoga is an Indian discipline designed to awaken the body's energies and promote enlightenment. Tantric sex also makes use of Kundalini energy to achieve unity between the practitioners and the Hindu goddess of feminine power. Astral travel describes any activity during which the soul or life force travels outside of the body. The hippie culture of the '60s, embracing diversity, Eastern religions and the sexual revolution, would be eager to learn these practices.

Ellie quotes from Through the Looking Glass, the book being read to her on page 15.
Dream quotes the fairy Puck, from Act III of Shakespeare's comedy A Midsummer Night's Dream. While Puck was referring to the folly of the play's young lovers, Dream is using the quote at face value and simply calling Alex Burgess a fool.
