It took me more than a week to deduce from the evidence around me that everything before my waking up was a dream and everything afterward was reality. There was no basis for distinguishing the two other than the growing pile of new events that seemed to argue against the drunk experience. Little things appeared, like the locked door, the outside of which I could never remember seeing. And a slip of paper from the probate court telling me that some person was committed as insane. Did they mean me?
