A personal experience on this scenario. My grand ma passed away peacefully and a TV and a DVD player co-incident stop functioning on the same day. The equipments have been serving her for past 15 years. There are a lot of co-incident cases happened. Timing, old friends that suddenly met and have dreams on her. I am recording down this incident for future reference when research is continuing.

Mean time, i have brought a magnetic field detector in the ER center during my visit to the public hospital. I have scanned a while in the room but nothing was detected except some medical equipment shown generating high magnetic field.

We are not sure it is real or a camera trick.  No harm can be a reference of study.
