I was curious which was more normal for everyone.
I'd classify, excluding my childhood, my switches to an alter and back as short. They last from as long as five minutes to about four hours. Four hours seems to be the longest.
And I wonder if how long they last is related to the environment. I hardly ever leave the house and /i consider my house very safe because you can't get into the building without a key or someone buzzing you in. The four hour length was when I had my first therapy appointment and Michael took over and got me home.
So how is it for everyone else? It would be interesting to compare.
