A Writer's Quirky Brain

I often wonder at the way my brain works. My grandmother recently passed and during her funeral service a stray thought pops into my brain. What are funerals like in my new fantasy world. This is just one example. These thoughts are like meteor showers and they come in all shapes and sizes. I see someone on the street and my brain creates a whole life story. A poorly written/acted/directed movie will kick my brain into overdrive. Before I know it, I've dissected the plot and planned out how I would have written the ending. I am not alone in this quirky behavior. Writer's just tend to think differently.
