Face on the Wall

Hi , My name is Gary Martin ,

I took these 2 pics myself.
I live in Northern California , U.S.A. I used a sony 5 megapixel digital camera to take the pics. The pics were taken on Wednesday, June 21, 2006,at 5:34:42 PM also it was an overcast cloudy day.

I think its a face that appeared on my wall for only about a minute, then it was gone and I have lived here for over 10 years , never seeing anything like it before .
I couldn't find a cause, no reflections of light because the blinds were shut. I don't know what it was.
