I would double check all your temps and make sure there's not a stuck eyecap on her but my guess is she is just restless. Possibly a substrate she could dig into or change of cage decorations and hides might help. Are there other snakes around she may be smelling or other pets around the cages? I have one blood who tends to be very active and odd compared to the rest as far as wrecking paper, flipping bowls, cage cruising.
