Are there any regions of interplanetary space where a human could survive without a space suit?

To clarify, is there any reason to believe that there could exist a nebula or gas cloud where the gases, radiation, and temperature could permit an exposed person to survive for any period of time without dying?

No. Even in a nebula the gasses are absurdly sparse, and not even within several orders of magnitude of the density we'd need to breathe. And that's assuming it's pure oxygen, which it obviously wouldn't be.
