If you could walk through a magical portal into another dimension, would you do it?

I suppose you'd want to know a little bit about where it is that you might end up... but then again, maybe curiosity would still be enough to tempt you.

I'm reading Neverwhere by Neil Gaiman at the moment. One of his lead characters is called Door, and she has the power to create portals into other dimensions.

It's an intriguing concept that got me thinking about the ways and means people – or people's minds – can travel to other places.

From literal teleportation (Chinese scientists have done it with photons) to just listening to music, I think there are all sorts of doorways to other places.
