Lapse explores the onset of unconsciousness and forgetfulness. I had been reading about how the alchemists noticed the human body lost a little bit of weight at the moment of death. They speculated that this was the weight of the soul leaving the body, and spent a good deal of effort trying to capture it. I thought I could do the same with a camera - capturing the moment of going unconscious. Then I began noticing things that were slipping into the unconscious world all around me.
