so i guess the phrase “in a better place” has been reserved for death.  
here lies a scenario where technically the phrase would work but due to this connotation, wouldn’t be advised to use.

(A Nursing Home)
Women: Hi, I looked inside my mothers room but I don’t see her. Where is she?
Nurse: She’s in a better place.
Women: what?!? mom!!!!  
Nurse: you can go down there if you want.
Women: what are you trying to say lady. i can go DOWN there! Let me tell you she was a very nice lady, and that whole jail time thing back in ‘66 was not her fault…
Nurse:  Your mother is in the new remodeled portion of the Nursing Home,located on the lower level. its a better place then her old room.
