We argue that spherically asymmetric bounce suggests several inequivalent directions of the time arrow upon the analytic continuation to the space-time with Lorentzian signature. It it shown that S-branes in the imaginary time emerge naturally upon the particular continuation.12 pages, 3 figuresHigh Energy Physics - TheoryGeneral Relativity and Quantum Cosmologytext
