For a person not suffering from DID, losing ones keys, while frustrating, usually ends with the wayward trinkets found and life goes on. For me, it is never so simple.
About 5 years ago, I "lost" one of two sets of car/house keys. They went missing on a warm afternoon just before I left the house to go to the grocery store. I searched for a few minutes and then just grabbed the other set and went on my way. Later, I looked for the keys again, then the next day I looked before work, and so on, until weeks went by and I finally wrote them off as having been accidentally thrown away (altho I did look in the trash, too). This happened just as my therapy began delving into DID and what it meant to me.
A year went by. My young alter, Smoke, was having much trouble dealing with all she has lived thru and to make matters worse, I had learned she would sometimes try to "disappear", by dieing or running away. She is always prepared for one or the other. My husband had walked out on me to be with his girlfriend and I was desperate to find the other set of keys because I wondered if he had taken them. I worried he would come take my car away - as a way to hurt me. I became frantic.
Then, one warm spring afternoon, I opened the back car door and there, laying on the floor, was the second set of car keys. Along with that, was a small suitcase filled with socks, underwear, a few cans of soup, many bottles of prescription pills (some of which are lethal to me), and money. Lots of money.
To this day, Smoke (who is 11) is always prepared for the world to end, or to dash away should someone try to hurt her. Smoke is not afraid of the dark nor does she believe there are demons in the closet or under the bed... Smoke knows that demons walk in thru the front door.
