I have a friend who has been having nightmares and so I decided to turn a toy gun of his into a dream weapon. I couldn't find any chalk so I used pipe cleaners to make a big thurisaz rune in the alley. I put the gun inside the rune and said "Whe enemies in nightmares lurk, against them may this weapon work. Abaxacatabax!!" And fired the gun when I said the last word. any comments on whether you think this will be effective? I will keep you posted on what develops...
