And although this kind of occurence is passe, especially to The Bermuda Triangle afficionados, it makes me wonder.
To anyone who has ever been out to sea, it does not take long to remember the loneliness, the power, the awe. You are in a Borderland of sorts, a land never truly conquered, never understood. Anything can happen when you are all alone, and, apparently, sometimes it does. And to pose the old quantum question: When a tree falls and there is noone there to hear, does it still make a sound?

Read The House in the Borderland by William Hope Hodgson. A bit of that feeling is in there.
