What's happening after one human being dies?

So you know how when you're under general anesthesia, the time just goes missing? Like you're in one place, then suddenly you're somewhere else? Imagine that phenomenon except you don't regain consciousness again. Instantaneous eternal oblivion.

We can actually never imagine death because a person experiencing it will not (At least as of now) cannot tell his experience to others. All we can do is speculate. Although, I've heard that in the final moments of your life, your memories play like a tape recorder. I don't know how true is that.
