Why does a moving train drag us when near?

When we are near the moving train,we feel that the train drags us,,,  at the same time when we are near the window side in the moving train,y the plants or trees which is near the railway track get outward movement or repel from us? plz explain which concept behind this act?

The dragging experience is explained using Bernoulli's equation.

As the train is moving fast, it creates a low pressure area. So, the surrounding objects get dragged from high pressure to low pressure  area
