waking up to find Fluttershy at the foot of my bed, first thing I would do is slowly scoot her up to my pillow and cover her up with my cover and let her sleep while I'm at the foot of the bed freezing.(yes i would freeze for Fluttershy). If i woke up to find she's gone I'll be back in my spot sleeping. If she's still there I would gently wake her up to ask how she got here and how long she would be staying, if so we would find a way to get back to equestria and I would say good bye and ask if I'll ever see her again, if not snap a picture for memories to come.
