Maybe the episodes were brought on by what she saw in her dreams, the bits and pieces of images that flew at her while she slept that she could never remember when she woke. Or maybe it was because she was exhausted in a way that no amount of sleep could cure. No one knew. If she was back in Hogsmeade in her own bed, she would be gently woken up by her husband and forced to swallow a damned potion she hated. It stopped the disorientation, the fear, the cold sweats, but only by making her sleep for several days straight. She loathed when he made her drink it because it proved to the world that she had weaknesses. She didn't want anyone to know the truth. They could use it against her if they did.
