In Isaac Bashevis Singer's short story "The Riddle", Oyzer-Dovidl remembers a dream where his wife, Nechele, acted like a young boy:
He was constantly remembering adventures from stories his aunts had read or told him, though now Nechele was involved in all of them. At night he dreamed of gipsy [sic] women, of robbers in caves, of sacks full of gold coins. Once it seemed to him that Nechele was male, that he saw under her lace drawers the fringed garment of a boy; but when he had tried to kiss her, she had clambered to the roof, nimble as a chimney sweep, and yelled down at him:
Crack your crown.

How can this dream be interpreted? What does it mean that Oyzer dreamt that Nechele "seemed male", and that she was wearing the "fringed garment of a boy" (presumably tzitzit)?
