Overactive Imagination..

    My overactive imagination..
So, I have been wondering.. Does anybody else have an extremely overactive imagination? I mean like, whenever I am in a situation, I come up with the most absurd things that could possible happen.
    For instance, I went to the store the other day with my grandfather, to help him get stuff and keep him company. We were walking down one of the isles, and I though "What would happen if there was an earthquake right now?"And elaborate mentally everything that would happen.

"What if the isle fell over? I would push grandpa out of the way, and make sure the pop tarts don't break. I freaking love pop tarts.."

     And, mind you, I am sure that everybody does this occasionally, but this is a regular occurrence for me. My mind may temporarily go back to my normal train of thought, but surely enough, it deviates from the path, and creates completely random scenarios that fit with the current situation.

"What if a robber came in right now with a gun? Well, the robber probably just wants money, so it would be best to go to the back of the store near the bathrooms. He'd never find us there! But wait.. What if the robber needs to pee or something? Bad idea. Wait, I think there are employee doors in the back that we could sneak out. But what if he was a suicide bomber! How fast would Grandpa and I have to run before the bomb went off? Surely it would have to be small enough to walk into a store...."

    I may be slightly exaggerating on the amount of times this happens, but you get the point. Does anybody else have this problem? I'd hate to be the only one..
