Our current state of physics can not define what the pre-BB state looked like. It breaks down at the pre-Planck-time. The standard BB model entails one universe only.
However, when you start talking about multiple universes, etc. , this would be more in the realm of string theory. Here with n-branes, all this is possible. One of these cosmologies, the Ekpyrotic model, postulates the collision of two n-branes causing the BB. Here we have a pre-existing universe into which at the area of the brane collison, the BB occurs.
However, it is all mathematical theory at the moment.
