new short film idea

I just had another idea for my short film as I was on a public bus, a man got on the bus that looked as if he was homeless, I immediately found myself wondering about what his story was where he was going and where he had come from. I got the idea that there could be a bus ill of people and the main character imagining all these people they never met in their every day lives. The thoughts that the main character is having fade in and out after focusing in one of the passengers.

This idea may be hard to be able to film but the main idea is there so I may try and play around with the idea and find another way of doing it that's more practical to film etc
