Unfortunately, the door goes both ways.
Rather than just sealing the god away, they created a brief vacuum in space time. Almost explosive changes in pressure created gusts of air that pulled them straight into the doorway. They bounced within an ever-changing tunnel. Were fate more cruel, they would have landed in the home dimension of the one they had defeated. They were fortunate that they instead were vomited out into another world. One similar to their own, but still wildly different.
Small clouds of dust rose from where they hit the ground. Their equipment clattered as they rose to their feet. The sights, sounds, and smells of the forest clued them in that this was not New York City.
"So what? Are we dead? Is this the afterlife? Seems kind of boring to me," said Peter Venkman, "So could someone explain to me how we went from a high-rise to the middle of...wherever this is? Ray? Egon?"
Ray Stantz, brilliant in a clueless sort of way, shrugged his shoulders. Egon Spenglar, however, was in the middle of examining the nearby flora. He glanced back at Venkman, pushing his glasses back on his face. "I don't think we're dead Peter. As far as I can tell, my vital functions are still normal."
"Yeah," chimed in Ray,"I mean, I don't feel like a million bucks, but I've got a pulse."
"Well that's good guys. Now I guess the next important question is, where are we?" Venkman gestured at their present surroundings, "Last time I checked they didn't fit apartment buildings with forestry. Either that or I've been getting screwed over by my building supervisor."
Egon retrieved his PKE meter and began taking readings. He shook his head as the readings started to come in. "The only thing I know for a fact is that we went from a high PKE environment to a low one. All readings are normal."
"So did we beat Gozer then?" asked Ray optimistically,"I mean we are still alive after crossing the streams."
"At the very least, we reversed whatever process summoned it. I'm thinking that when we 'closed the door' we must have swung it the other direction, pulling things in rather than sending things out."
Ray was dumbfounded. "A reversal of dimensional polarities. This...This is amazing! Oh man! If we can find a way back home, the implications of this would be staggering!"
Peter walked over and placed an arm over Ray's shoulder, shaking his head. "Ray, Ray, Ray...I think you've forgotten that we don't even know where we are. I kind of doubt that we're even in the state of New York, much less the city."
At some point Egon pulled out a calculator and was currently crunching numbers. "I calculate the odds of us even being in the same dimension as being 0.001%"
Peter continued, "Also, has any one seen Winston? Thought he was with us?
After a couple of quick glances there was no sign of the missing Ghostbuster.
"Geez, I hope he didn't get too seperated from us. If he's in a different dimension from us..." worried Ray. He was soon interrupted by some rustling from the bushes.
From the leafy depths walked out Winston Zeddemore. "I'm right here guys."
Everyone breathed a slight sigh of relief. Until Winston continued, "And I, uh, brought along company."
Two individuals, both faces concealed by masks of some sort had Winston held up at knife point. They wore padded green vests over some sort of loose fitting tunic. Both were wearing headbands that bore a stylized leaf in a metal plate at the center.
Peter, Ray, and Egon reached for the neutrona wands from their packs. They soon found knives held to their throats as more of these masked characters appeared out of nowhere.
The Ghostbusters glanced at their captors in nervous silence. Winston finally broke the silence.
"I better be getting overtime pay for this."
