Sci-fi scene - what does this mean?

[Billy Paul]

There's a scene while Donnie is hypnotised where you see the ocean with some big, grey, square futuristic-looking things sticking out of it. (Or hovering above it?)

First impression was that this scene doesn't seem to have any relevance at all, but I'm beginning to realise that everything that happens in DD has some relevance to the plot, (even things going on in the background!)

Does anyone have any idea what the big, grey things are? and what relevance does this scene have?

Any theories appreciated!
Thanks,
BP.

This is a hallucination, in which Donnie forsees the school being flooded; the "ocean" is the water from the flood and the "futuristic grey things" are the lockers in the school hallway. The image looks a bit wierd because it is based on a painting by Scott Mutter. You can see both images at this address:

Oh, cheers! That makes a lot of sense actually.
