You know in fact, I really wished to participate in this contest and have already drafted few stuffs in mind, but after going through your story | dropped that idea. For me this is an excellent piece of story that really connected to the topic. You should really try in writing such stories or even Novels seriously as you have a real flow in presenting the myths and fiction and connect it with present.

You must had been to India once, or you might read about India a lot, otherwise there is no chance of you mentioning an Indian city which have the Bay of Bengal on its side and an Indian who taking the main charctor along with him to the other world.

I had gone through somewhere which mentioned about the sentinel island and people, but the story thread have a good beginning with this context.

The other 5 worlds, their names, incorporating flying saucers which everyone in this world is aware about and finally the open lake with the access back to the earth is simply awesome.

It seems the story had ended without a convincing conclusion if we think about quality of the story you written, May be it is enough for the contest.
Cheers...
