haha, thats great! I know exactly what is going on I feel.

On the left hand side, your outliner, you will see a menu that says "Display", click on that. Now just click on "Shapes", this is to be able to see the shape nodes in your outliner.

What are shape nodes? Well, overtime for example you create a geometry you have a "transform node" and a "shape node"..... transform node is what holds all the numerical values of what position your object has in correspondence to your scene. Now the shape node is more towards the material side of the object and the actual shape of the object.

Somehow you managed to put that camera's shape node into the geometry's transform node. Once you turn on "Shapes" like I mentioned earlier, just click the plus button next to your geometry. You should be seeing a camera shape node in there, click on the item and delete it. That should do the trick!
