2. Sleepless in Seattle I heard an interesting story on the news last night about a guy from Seattle. In this story, Bryant was having a problem with recurring nightmares. Bryant reported that he was having a nightmare every 19 days about 19 ghosts scaring him out of his wits by jumping out of a 1919 Hupmobile and saying "boo" 19 times. (Don't ask me to explain this - it's Bryant's nightmare!). He was also having a nightmare every 13 days about 13 black cats crossing his path in front of his house, located at 1313 Thirteenth Street. He had a bad week in May, when on the night of May 13th, he had the nightmare about the 19 ghosts saying "boo" 19 times. Two nights later, he had the nightmare about the 13 black cats. Bryant knows he can handle these nightmares when they occur one at a time, but lately he's been really worried that they might both occur on the same night. Do they ever occur on the same night before the end of the year? If so, on what date?​
