I know the feeling. I can be standing at the front of a vehicle working on it. Have a wrench (or any other tool) in hand. Should I lay it down in front of me, merely turn a little right or left, then right back to where I was the working, the wrench (or tool) is no longer to be found.
Keep in mind I didn't walk away, didn't even move feet, just merely turned my head for a moment and the tool gremlin had taken my tool from me.
And occasionally I may never see that tool again.
I swear they're out to get me.
