Crowded trains / train stations are good spots for contemplation

[RMQualtrough]

I don't ride the train much, but when in a very busy spot like that it is easier to imagine removing perceptions from the world.

E.g. you can close your eyes (which isn't the same as being blind, we see black, but still), and then notice the entire audience sound is like when you zoom in on the people on Rollercoaster Tycoon 2 or Zoo Tycoon or something (lmao), and imagine if you removed hearing and went deaf, and see how people just vanish.

And you can see that you are looking at nothing but a product of your own mind. Even a materialist understands that what we experience is a product of the mind. It's interesting to seriously realize it sometimes. Especially in crowded settings like that.
