I wouldn't sail this ship if I were you
1. You journey into a parallel world just beside our own. Someone tells you that you are the only person who can save this world from disaster. It turns out that this is a thing that the inhabitants of that world find hilarious to say to inhabitants of your world, for some reason. You go home feeling a bit grumpy.
2. You journey into a parallel world just beside our own. It is quite nice. Sometimes you still go on holiday there, although generally only on day trips because of the difficulty of exchanging currency.
3. You journey into a parallel world just beside our own. At least you think you have. The two worlds are so similar that you cannot tell the difference. It is possible that the old woman operating the portal is a con artist.
4. You journey into a parallel world just beside our own. You meet the parallel-world version of yourself and sleep with them. You cannot decide if this counts as masturbation or not.
5. You journey into a parallel world just beside our own. It has a strain of influenza that is slightly different from our version. You bring it back into our world, causing a global epidemic that kills fifty million people.
6. You journey into a parallel world just beside our own. You discover a huge conspiracy by the cognoscenti to keep the parallel world secret, because you can get really good cakes there and nobody wants them to run out.
7. You journey into a parallel world just beside our own. The parallel world just beside our own also journeys into you. You become doomed to spend the next few billion years as an honorary universe. It is a little uncomfortable, but you think you might get used to it.
8. You journey into a parallel world just beside our own. It smells repulsive. You return to our world and warn the next person in the queue that they might not want to go in there.
9. You journey into a parallel world just beside our own. The inhabitants are charmed by your unusual skillset for a human and you get invited to all the best parties.
10. You have already journeyed into a parallel world just beside your own. You made the outbound trip somewhere around January 1, 2016. I would have thought you’d have noticed by now. There’s still time to go back, if you can find how you got in in the first place.
