@MJG017 @my radiotherapies really triggered my cPTSD as there were similarities to abuse so I was unable to close my eyes as I was went back to being hypervigilant. But that story is not for this thread. But that made me think at least some other people will be having similar reactions and would perhaps benefit from a calming distraction. They replace the normal ceiling tiles so they are quite big. The department has told me since that other patients have benefited from them. So I am pretty happy if I can in some way help another human.
