I am glad you found comfort in seeing your white feather and hearing the songs you associate with loved ones. Like others, I don’t think that someone who has died has brought about these experiences, at least not in the strict cause and effect sense of science. Nevertheless I do regard such experiences as significant.
In stressful times, and particularly after bereavement, there is a tendency for the human mind to engage in magical thinking. It restores a sort of order and meaning to the world when we least feel in control. Joan Didion wrote a book called The Year of Magical Thinking about her response to her husband’s death and the mix of rational and irrational thoughts she experienced.
The psychotherapist Jung has written extensively about what he calls synchronicities or meaningful coincidences. (I have just been reading about his ideas on synchronicity so your post describing feather and song synchronicities creates a synchronicity for me!)
In particular, Jung recalls the unusual appearance of a golden scarab at his office window just after the patient he was seeing at the time spoke of dreaming of such an insect. Jung was able to catch the insect and hand the patient ‘her’ scarab. The experience affected both of them profoundly. His patient was subsequently able to escape the overly rational mindset she had been trapped in.
So this kind of associative dreamlike thinking can be very healing. Often what is important in life is not so much what happens but the stories we tell ourselves to explain what happens, the interplay between inner and outer worlds. It is because our feelings and actions are influenced by these stories that techniques like CBT are useful.
Restricting our notion of what constitutes reality to the prosaic unfolding of the external material world without reference to inner experience is not always helpful.
When my DS was little I used to read a book called No Matter What by Debi Gliori to him at bedtime, the last lines of which are:
Small said, "But what about when we are dead and gone, will you love me then, does love go on?"
…Large (replied) "Look at the stars, how they shine and glow, some of the stars died a long time ago. Still they shine in the evening skies, for you see…love like starlight never dies…
I think this is a truth well worth embracing.
