Unwanted but good multiple exposures

First, I shot in Monterreal, after a few pictures, I realized the red light wasn't turning on anymore ( I thought...) so in order not to waste the roll, I rewinded it a bit, forgot about this and another day, I shot some pictures in Parras (wine stuffs) and when I got them processed, I realised the camera was working good and I got some good multiple exposures! :)
