That's what happens as I swipe up. What happens with a straight
gentle swipe up that goes goes off the top of the screen? Is there
any other unlock method required such as a PIN or pattern? I have a
pattern set.

Its default was just the swip to unlock, I added the pin thinking it
might avoid the swipe, but it didn't. Whether it needs or doesn't need
the pin to unlock, the swipe remains tricky to get past.

I'm not sure what the pattern method is, but the NOOK lacks a camera.
