He looked around him wildly, as if the past were lurking here in the shadow of his house, just out of reach of his hand
Very similar imagery to the image used when we first met Gatsby. In the first chapter he is “stretch[ing] out his arms toward the water in a curious way” towards the green light. The same idea is used here to reaffirm that Gatsby’s green light, his American Dream, is to recreate the past and everything that comes with it (i.e. Daisy).
