Lysol, any odor can imprint

Recently a person wrote me about their having had ~ 15 electroshock treatments and¬†can only recall the last one. After that 15th treatment they awoke while smelling Lysol. Since then any smell of Lysol rekindles the memory of that last treatment … an imprint, a¬†hallmark of PTSD. As their life unfolds, they may notice other triggers, possibly even from a treatment (1-14) otherwise forgotten.
