I have had a similar experience and I have been with friends when they had that sort of experience. It might have to do with what you got drunk on. Not sure about that. Basically, you are able to function. That is, make decisions and take actions. The reasoning sometimes being very strange. But making "sense" in that altered state. But, the brain is not storing any memories or only brief flashbacks. So the executive parts of the brain kept functioning, i.e. you did not lose consciousness. Brain studies demonstrate that different parts of the brain are involved in different functions. It is well known that alcohol can lead some people to lose inhibitions. Some people become more aggressive, others just want to sleep. So in the situation you describe as blackout, memories were not formed.
