Do we actually know what happens to consciousness goes during those times, where does it go?
Well human consciousness is not an object, but a process. When conditions for its arising are not met, it disappears, much like a flame disappears, it does not go anywhere. So under a strong chemical imbalance say a heatstroke, the consciousness process breaks and it ceases to exist.

The question is not "why should death be any different," but is death different?
To paraphrase Clint Eastwood in that Dirty Harry movie, well, punk, is it?
Death being the destruction of the body, it follows that consciousness must disappear as all processes are disrupted.
