Is there such thing as "Too much" moisture in your skin?

About a week ago I got severely sun burned.. It started up being just a little pink and as usual my skin dried up and started pealing then blisters appeared shortly after. My skin is starting to look really puffy now because the moisture is trapped in my skin. I took a shower and the water seeped through my skin and filled up in like pouches. My skin falls off by the touch I can simply rub it and it will fall off. Im very fair skinned and its starting to worry me can somebody help me? And I have very little pain besides slight stinging
