I am not sure how much of a personality a bat has, but it's a distinct property aside from eat/shit/replicate manners of most lifeforms

Reanimate a frozen dog. If it is able to recognize its holder, and shows the same personality (like shitting in the same old spots), i would have to reconsider...
Obviously, dog re-animation is not yet possible. If you can do it for a dog, you would 100% able to do it for a human (not much difference in basic biology there).
However, there is no principal impossibility of memory preservation in a frozen state.
Here is one experiment...please don't poo-poo little worms...they taught us a lot and, basically, show us they way to research on bigger organisms.

Would be spectacular if human memory could just be read out like bits and restored like data backups.
