I was just a child, and received a partial body sighting visit from my Great-Grandmother, in the old Bedroom she died in, years ago.
Her identity was confirmed and validated by photographs from some old family photo albums with the help of my Mother.
Nothing since then has been involving a true sighting, all other "visits" have been, my name being called, a touch to the face, the scent of perfume, and so forth.
Nothing is ever so strong as when you're a child, then it seems, as you get older, it becomes more difficult to receive a "visit" of any clarity or magnitude as an Adult, at least for me it has.
