Wow, SusieShoes, your hospital sounds wonderful! I read your link about it. I'm glad you are going to have the Reiki; I experienced it some years ago from a friend who had studied it. I cannot remember whether she actually touched me, or whether her hands just "hovered". Either way, it is gentle, no pushing or pulling. When the nurse is ready to start, get into a comfortable position and try to relax your body and your mind as much as possible, and just let go and enjoy it! Yes, it is healing energy coming into you from the person doing it.
I am treating my stay in hospital as a "holiday", even though holidays don't usually involve surgery and discomfort! Well, we won't have to think about cooking, washing up, cleaning etc etc. Just relax, rest, do our exercises, and let the healing happen!
I was told I'd be in the Orthopaedic ward for a few days, then transferred to the Rehab. ward, making about ten days altogether.
I've not heard of a dog being allowed into a hospital! Although I've heard pets are allowed in some nursing homes, and the patients benefit from their company.
