EJ - I have a feeling that the running into walls thing may be because you feel frustrated at having this situation with Molly repeat it self over and over. Perhaps you feel as if you are "running into a wall" with no idea what to do to help her? Even though you are bringing her to the vet, i bet it is still frustrating to have had to rush here there several times.

I have heard that falling dreams mean you have a situation that is beyond your control - and this could apply here too i think.
