A Ph-shift, or Phantom shift, is a therianthrope-related occurence, when a therian feels the limbs of their phenotype. They can feel their animal limbs, yet they do not physically exist.
A ph-shift can be brought by similar factors of a m-shift, occur randomly, or can even happen at will.
Many therians say a ph-shift is the closest thing to a P-shift.

I had a ph-shift recently, and it can conflict with the human limbs.
