The Sleep Thorn
Old spell from Icelands reads on how to make Svefnthorns: "Take the heart sac(pericardium) of a dog; pour pickling broth into it. Then dry for thirteen days, in a place where sun not shine in it. When the one to whon you wish to do this is asleep, hang this in the house over him completely without his knowing it."
Rune alphabets/symbols are used to wrote this magic. The norse God Odin use a Svefnthorn to sink Brynhildr, the valkyrie into a slumber so he could save her from fire that encircles her.
Mythical magic transcripts/runic language based on norse mythology.
Those who use these magical words are deemed to sleep/not awaken for a long time, thus living a life in a dream state, another form of reality.
