gefen, I totally got what you were saying. Who are we to say it was NOT a siman from Ayala O”H or even from Hashem, to let her family and friends know she was present? When my father O”H was niftar, we had MANY such simanim throughout the shiva, things that could ONLY be associated with him and no one else. If this gave any comfort to the aveilim, I certainly would not want to burst their bubble by making light of it.
What a tragedy!
