It's hard to describe the experience.
I have never had loss of memory and 'awakened' somewhere else than when i entered the dissociative state. I believe that it is some kind of defense mechanism developed by my younger self, so that whenever i find myself in situations that are emotionally stressful (which can be anything from small to bigger issues, e.g. fighting with your partner or even talking about how dissociation feels like), I will automatically enter this state in order to shut out any harmful emotion.
- it feels like my forehead gets cold. The back of my head and fingers get tingly, and while I would describe it as not being able to feel a thing, it is as though my body is in a state of panic.
It's contradictive, I know...

Sadly, it also renders me unable to feel any positive emotion as well. When I enter this state, I tend to feel frustrated by the lack of understanding of my own mind and body. Overall I do not see it as a big problem, since dissociating can help me too. In certain situations I prefer being separated from my emotions, allowing me to act out of pure logic and reasoning. It's extremely situational how i percieve it.
