If I ever pop a blister by puncturing the dead skin with something like a needle to let the fluid out, it seems like several hours later, the same dead skin is pocketing fluid again. Why is that? Dead skin shouldn’t be able to heal like that, right? Shouldn’t the hole remain there?

The fluid is there to protect the skin underneath it while it heals. It’s your body making a little pillow to protect the damaged skin.
