Someone knows details about my childhood that I never posted online

Dear Delyara, For the last month, an anonymous account has been sending me messages containing details from my childhood. The name of my first dog. The color of the bicycle I had at nine. A nickname only family used. Nothing threatening yet. That almost makes it worse. I blocked the account; another appeared. Police say there is not enough to identify a crime. My siblings swear it is not them. My parents are dead. I have searched old classmates, relatives, anyone who might think this is funny. Last night, the message said, “You still hate peas because of your aunt’s kitchen.” That is true. I have never told that story online. I barely tell it at all. I am beginning to question every person who knows me. The messages have turned memory itself into evidence that someone has access. I sleep with curtains closed now. I check the car before getting in. Maybe this is an elaborate prank. Maybe someone from childhood simply wants attention. What frightens me is realizing how intimate old facts become when they return without a face attached.
