Staten Island Tide:
In water, we see movement, and although it would seem to all go in one direction, attention shows where the points of reference go. This clip shows the tide coming and/or going along a creek bed, but due to the various points of reference it is harder to definitively say which. (I also did not put the tide line in, so you do not know how far from the actual shoreline this place is, thus potential lag in the water movement.)

Staten Island Railroad:
The movement in the second video is of one of the train rides on Staten Island. Although you will not see the second point of reference directly, you can make an assumption of what the scenery passing the window (and thus indicating movement) looks like, based on the light and shadow on the floor. The context I’ve given you and your memories/experiences of trains and shadows assist in your ability to perceive the movement.
