Out of the ordinary/ exceptional/ irregular/ unusual
Abnormal. Different from its origin (in the source: It comes out of the womb. A term for a baby born by cesarean section).
("For a child born by cesarean section, days of impurity and days of purity are not observed, and no offering is required for him. Rabbi Shimon says: This is like a child born in the usual way to all women" — Niddah 5a, and also: "At first, the 'golden throne' was embarrassed to reveal before his great admirer and chief supporter the out-of-the-ordinary dream, not to say the implausible one" — H. Beer / To the Place Where the Wind Goes, 117)
