My situation wasn't exactly one of 'mortal danger', though I was in danger of losing myself in a way, I wasn't in a position where I would have been considered 'dead' or otherwise.

However, it is my personal theory (and one I've noticed shared by others around the place) that our consciousnesses have been 'copied' and transferred to other bodies here. If this is the case, the 'original' would still be continuing on in your home dimension unaware of your existence. In that case, leaving this facility and dimension would have no effect on your current form, unfortunately.

But there is always the possibility that my theory is incorrect, or that I have overlooked something vital. And should my theory prove to be accurate, then it is equally possible to create for those of us in human bodies new bodies of our natural species and to initiate a similar transfer into those. It is something that has been shown possible with my people's technology, so I should easily be able to duplicate it.
