A Caregiver's Dilemma

I work the night shift at a care facility, and sometimes I get these bizarre urges to go above and beyond in my role. The other day, after settling a patient who had trouble sleeping, I found myself whispering soft commands and encouragements that went far beyond what was necessary for them to rest. It felt odd, but also oddly comforting, like there was some hidden understanding between us. Does anyone else experience something similar or is it just me? Am I crossing lines here or is this more common than I think?
