What if a tiger jumps into my back garden

So, I was sitting out in the back a while ago. Reading my Kindle and enjoying the long evenings. When suddenly, in the middle of a paragraph, I thought, what if a tiger jumps into my back garden. I have no idea where this thought came from, but I spent the next five minutes or so going through what might happen.

I've no idea if I could get the back door open in time to escape into the house, but let's say I could. If I rang the guards, they'd never believe me, and it could take ages to convince them to come out. And what if the tiger broke through a window? I'd have to run out the front door and close it behind me and then race up to the local Centra. But they wouldn't believe me either until the tiger arrived and, by then, it would be too late to close the doors against it. So, I'd be trapped in Centra with a tiger, and you just know it would go for me first.

Totally ruined my peace sitting outside and I kept thinking about it until I gave up and came back in. I know it's probably not going to happen, but every time I tried to go back to reading, my mind would wander to the tiger again.

This happens to me all the time. I'll be wandering across a bridge and suddenly will think, what if this falls down. Or along the Liffey listening to the radio until I think, what if somebody throws me over the wall.

Obviously I'm completely batshit crazy, and, so far, I've never been attacked by a tiger, fallen through a bridge or been thrown into the Liffey, so there's no basis for my fears.

Just wondering if anybody else gets these random thoughts. They're not always negative either. I'll get good ones too like what if I find a winning Lotto ticket or a friendly puppy and get to bring it back to a loving owner and then spend some time going through the different things that could happen.

Anyone else???
