This looks like an interstitial loading scene that you'd get really excited for only to have before a really boring 'top down' view of a lighthouse that has a spartan layout, something like a spyglass in a chest, a frayed rope, and an oily rag. None of it really makes any sense, but nothing really is so far out of place that you questioned it.

Later, this same scene will appear with a dark blue sky and a yellow 'light beam'.
