Spiritual Forums - Smart phone communication

After I got back home a few hours after my wife had left her body in the hospice, I sat down on the couch and cried, i then noticed out the corner of my eye my smart phone display was flashing on off on off etc, I picked it up and tried to switch it off but it wouldn't go off even after trying to do the usual method of pressing volume and off together etc, the phone became unresponsive so i put it back down again, then i saw her Whatsapp profile picture pop up and even though i hadn't done anything and Whatsapp wasn't even open, it remained like that flashing on and off for a few minutes before returning to normal, a few minutes after that I can only explain a feeling of euphoria came over me and a knowing that it was my wife, i felt inside that she was telling me that she had made it and was alright. I had talked to her about spirituality and I always tried to reassure her that there was an afterlife and she would see that life does not ever end. I only say this here because most people would say that grief does strange things to people and put it down to that but I felt and will always feel that she was sending me a message from the other side. We were inseparable in life and we both hated being apart from each other, we always came together like magnets, we both felt at home with each other.
