A different type of missing image issue...

Hello, I've had images with the exclamation marks and have had to relocate them before, but this is something entirely different.
In the library module, I was reordering some photos between my 2nd shooter and myself for a wedding.  I had 22 photos selected and was moving them to a new section of the wedding.  I dropped them and they dissapppeared.  Now, they are still there in the folder on my hard drive (images 892-914).  In my lightroom folder it says 916 of 957 photos (because there's some stacks).  I've turned off all filters.  I've tried to see if they are available to import, but they are grayed out as if they are already there.
I really don't understand what's happening.  I went to ALL PHOTOS in lightroom and searched for the filenames, but they still don't show up.  Help?
