When my grandmother passed away. was on no medication what so ever. she told my dad “ i see you george” my dad said who is named george as well he said mom im right here. she goes no your dad george he is dancing my grandmother reached up from laying down but reached to the sky and said george im coming. she fell back into bed and passed away. My dad said it was the most amazing feeling he ever had and my grandmother died with a huge smile on her face.
Maybe I am not that far off on my theory.
