You have been on my mind Dee and I often checked your page to see if you posted. My deepest condolences of the passing of your brother.
The three knocks as a warning of a death has been one experienced starting with stories my grandmother told me.
The trouble with the premonitions is we never know who is leaving this planet. I guess it is meant to let you know the future cannot be changed and the death time is casted.
Please take care my dear friend and know others share your sorrow. ❤️
