What is INSIDE a Wormhole?

IF they were real, would wormholes work in the way that they do in sci-fi (for all intents and purposes "teleportation", travel without movement, FTL, immediately "appearing" at the other location), OR is there space, time, matter inside a wormhole?

If a wormhole is meant to circumvent light speed by practically "teleporting" mass from one place to another then there should not be a passage of time and space inside it. One should step into the wormhole and at the other location an observer would see your leg instantaneously coming out of another wormhole, right?

Or is there a "place and time" in between, where one could potentially hang out for a while, before stepping out to another place, or even back where you came from?

In short I'm trying to create a place that is outside of reality from which one could then step back into reality at any point (not time travel, just space travel). What do you think?

Sub-question for extra xoxo: If you could hang out inside the wormhole could you somehow "decide" in there where to come out, or is the exit of a wormhole predetermined upon its creation?

EDIT: This is an August 2015 article. First step towards creating a real wormhole?
