It sounds as if she may be blue, when in blue snakes tend to hide on the cool side.

Getting ready to shead

Young corn snakes tend to shed every month or so, give or take. Yours sounds like it's entering a shed cycle.

The call it "Blue" because most non-amelanistic snakes take on a bluish tint and their eyes glaze over in a grayish to blue haze for a period of several days. Snakes with red-eyes do the same, except it's more of a "Pink" than blue, and can be harder to notice the onset in the beginning. Then everything will clear up for a few days before they finally shed.

Your snake is extra eager to hide during this period because it's vision is obscured by the hazy eyes, which in the wild would make it easy pickins for a hunter. Some are more laid back about it, but yours seems to want to wait it out in seclusion.

At my store, all the snakes like to hide under the waterbowl. I think that may be because they don't have any hides (Yes, I've argued this point with them a hundred times, but no luck yet, UGH!) I noticed the ones that are under the bowl and not squished between the bowl and the back wall are the shedders though, don't know if it would make a difference or not...

I also think it has to do with the fact that the waterbowls provide a snug pressure.
