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.
