What you see is what I believe to be a ghost. It takes a few seconds to find it, but when you do it just stands out. Like one of those optical illusions in the sunday paper that you have to gaze at. At first it took my wife 3 minutes to find it. Now she can pick it out at a glance.
To save you some time, concentrate around the left side of the baby crib. Best not to focus too much on one spot. Look around the crib and toward the window. Click on the link below for the picture. Best to enlarge (Press F 11). For an added touch turn up the volume on your PC. You can actually hear it. It sounds like a faint out-of-breath whisper. Remember to turn your volume up, or you may not hear anything. Look long and hard before you doubt. It may take a minute or so before you pick out the ghost so give it time...
