Scientists have incomprehensible theories about parallel universes, ripples in time, relativity, and probability. Ordinary people think, while any of those theories is possible, strange events are just our own imagination messing with our heads, a reaction to drugs--legal or illegal--fate, or merely coincidence. Of Unknown Origin is a collection of stories based on actual incidents which defy explanation or, at the very least, logical explanations. They could be examples of any one of the above theories. Call them mysterious or a brush with the supernatural or just plain coincidence, these stories will give the reader something to think about or, at least, to be aware to of the next time they encounter something of unknown origin.
